WOW this laser really blew me away, because even though it's only $15 it actually performs quite well, the beam quality is not the best, the beam is not exactly centered ( that could just be a one of) but for that amount I'm still impressed with the overall build. Because the whole body is made of aluminium so it feels quite sturdy when it's all screwed tight. The only real problem that I found with it is the focus. Because to focus you have to "unscrew" a top portion of the laser, more specifically the part that is in between the on/off push switch and the knurled cylinder at the top, for me those threads felt rather loose at first so i was wondering if that was correct but then i put a pice of clear tape on the threads and now the problem is sorted. So now i can focus the laser to a really fine point and as they say on the product page with the laser focused you can light a match on fire even without putting black marker on it. And even when the laser is not focused it can melt darker insulation foam panels or styrofoam with black marker on it. So definitely not a toy and safety glasses are recommended, although i found that od4 glasses block-out the laser light entirely and the od3 glasses from sanwu are not the best but better than nothing for the start. Overall for what you pay this is a decent laser would recommend!

Ordered two sets of 200mw 650nm(red) lasers with glasses, Sanwu said they would need time to process and craft the order before shipping so I wasn't expecting my order to arrive when I wanted to, turns out from the moment I placed my order to the moment it arrived all the way here in west Europe only 6 days(total, not business) have passed, which is nothing short of incredible. On to the laser, the build quality is excellent, the laser is built up out of different parts that are all easily detachable by simply screwing them apart, you would expect a construction like this to be flimsy but it is not. It's extremely sturdy in both look and feel. For only 20 bucks you get a 200mw laser with an included and detachable beam diverger/focuser, which works wonders for increasing size or reducing divergence for burning. In addition to that the laser also comes standard with a cap that creates a spread pattern of dots which can be a lot of fun, as well as a lock and key mechanism for rendering the laser inoperable for safety. I don't have a way to measure laser output, but I am familiar with the power of 100-150mw and 500mw lasers, and based on that I feel like this laser does indeed output the advertised 200mw. I am nothing short of impressed, and fully convinced that this is a company safe to purchase the more expensive series from too. 5/5 would recommend and buy again. WOW!

Just as expected. It does not appear "blazingly" bright when indoors or in broad daylight, but it is dramatically different at night, or in a dark room. The beam is easily visible, and it will light up a large room, making anything florescent glow. I have a generic "laser 301" from ebay with a " 200mw" sticker on it. It is nothing compared to the Sanwu laser. This is now the fifth laser I have from Sanwu. Always as good or better than advertised.

They got my order wrong 2 times and half of the Lasers I got didn't work ( wouldn't go together properly to connect the circuit ) By the 3rd time I've given up.

I ordered the three color combo along with the set of five different effect caps. The green and red lasers were very bright but my purple one was faint, so much so that you couldn't see the dot from more than a foot away. After trying different batteries and adjusting the focus, I took a picture and emailed Sanwu about it. They promptly sent me a replacement which was much brighter, on par with the other two. While I don't have a power meter to test it, when focused the purple one is strong enough to burn dark colored objects or be painful to shine on your skin. The housings are solid overall though the buttons are slightly loose. I like that you can adjust the focus, as well as remove a section of the housing if you are using different sized batteries. Overall while there were some minor quality issues, the great customer service and incredible value more than made up for it. Comparable powered lasers from other companies would easily be in the $100 range, so at $15-20 apiece these are a great deal and the perfect starter kit for a beginner while still being strong enough to be interesting for more experienced users. I was very happy with this purchase and I definitely will be ordering from Sanwu again in the future.

I ordered the combo, and got 1 red and 2 greens. Not sure if COVID and the Shanghai lock downs affected anything, so I'm happy. Being a laser novice, and wanting to use them mainly for astronomy, I'm more than happy with the performance. The green laser definitely works well as a star "pointer". Very cool, and more than powerful for my needs. Can't wait to get my Striker!

This is not a Sanwu Stryker so don't expect it to be. It is a $15 laser. It will burn! I ordered the 405nm 100mw and you can focus this beam to a very fine point! These pictures show me lighting a red tip match with ease.

There was no battery in my package even though I ordered one. Thankfully, my LED flashlight battery fit. The laser works as advertized and is good quality.

I guess for the price I shouldn't of expected much but normally sanwu has pretty great quality to price ratio. unfortunately that doesn't seem to be the case with these. Its quite odd since they have good reviews, but maybe I got some duds. First major issue is I got the combo of all three lasers, and the 405nm was missing the all of internals to the keyswitch making it unusable without swapping it out of one of the other lasers. I contacted sanwu about the keyswitch and the other missing item (the second major issue) and after a week they contacted me and asked for pictures as proof. They told me they would send out another one, which in itself is frustrating because shipping took about 3 months. Its been about 4 months now and I haven't received my new keyswitch or the other missing item. The second major issue is I ordered a beam expander with the adapter needed to use it on their Striker series. The beam expander does work on these lasers but they did not send the adapter I paid for so I can't use it with the laser I actually wanted it for. Third issue is the output on the lasers I recieved is not as advertised. The green one and purple one is 50mw, the red one is pretty close to rated at 150mw. I collect lasers so I have many others to compare to it to, but I dont have an lpm to know exact values. The 405 is the most disappointing one, because the beam characteristics/dot is awful and huge for such a low powered laser. The descriptions of these lasers is a bit misleading I wouldn't consider any of these to be good at burning things, the purple one can't even pop a black balloon. The last issue is the quality of the threads on the focusing mechanism on the front, its so sloppy and loose that with the slightest movement the focus changes drastically. Which makes it very hard to focus and burn anything even if they had the strength to do so. All in all stick to their more expensive lasers, even with the great low price the quality issues are just not something I can recommend even for a beginner.

I bought the combo pack of all 3 lasers. On the web site, it states that there are specific directions that the batteries get inserted into the bodies depending upon the wavelength of the laser unit. All 3 lasers came unmarked so there was no way to determine which laser was which. By pure luck, I chose the correct direction to insert the battery into the first unit and it happened to be the green laser. Why not put a simple sticker on each bubble wrap sleeve that indicates the wavelength of the laser inside??? (Unless battery direction isn't that big of a deal...) Also, the web site does not state that the power button needs to be held down for the laser to stay on. I had hoped for a push button, click-on, click-off button. The lasers are well made, and I am happy with my purchase.

The shipment has arrived well. And laser tested and approved.

Great build quality all the fittings are crisp and tight. The laser itself is incredibly bright, I am very pleased. Money well spent! I definitely will be buying one of the more expensive models on this site next.

The lasers are great for the price, I got the 3 laser combo. Great starter point for beginner Wavelength Collectors. I especially like the red. We all know the greens. The violet is least visible but that is absolutely normal for this wavelength. You can not find better quality for this price. The shipping is good. Waiting for your next budget builds :P

shipment was good. i got a confirmation within the 10 days they mentioned. and it arrived a week later. came in a double brown envelope with some bubblewrap. about the lasers themselves. i was a little dissapointed at first. on first glance they felt cheap. even though at closer inspection you can see they are pretty decent quality lasers. the button just felt cheap. but the lenses are a bit medium. it's a verry wide beam so it's a bit hard to burn something unless focused to a specific distance. my older laser (bought from warnlaser) has a much more compact laser and can burn over a larger distance without having to refocus. it was sold to me as a 200mW laser but someone on the laserpointerforum said it was more likely to be 50mW. however it's stronger then all 3 of these colors combined. (litterally. brigther beam and brighter dot) the green is verry visible. but out of the 3 struggled the most to burn a hole through tape. the red has a somewhat visible beam and a verry visible dot. and the only one that managed to burn a hole without focussing. and burned fast with focussing. the purple one has a nearly invisible beam and a hella bright dot. (glasses reccommended for all 3 lasers) the only downside to this sale is that the duty cycle is not mentioned anywhere. and that there is no clear plastic cap to keep the dust out. instead of the manual spinning pattern cap that comes with it. red is the only one you can feel the heat from on your hand. (while in contrast my old green one from warnlasers feels like someone poked you with a needle after 3-5 seconds) in the end i am just as happy as i am dissapointed (dissapointed because of unrealistic expectations that i had) . would order this again. deffinatly worth the price.

Great laser for the price! I don't have a meter to confirm the power, but it looks maybe even brighter than I would expect. My only issue with this laser is that the focusing lens is loose unless it is focused at its farthest distance. It makes it nearly impossible to precisely focus nearer without carefully holding the lens very still. Otherwise, a great laser! Even 100mW could be dangerous for your eyes. Safety first!

I ordered a green 100mw one with the caps. It's so much brighter than I thought it would be! I have a noname pointer ordered from GB, it's quite bright, but dimmer than this. The quality is good, my only complaint is that you should depict on the body how the battery should be put in, I mean the polarity. I definitely recommend getting one!

I ordered the 200 mw red laser. The laser is very good for the price if you don't have to buy the accessories. The batteries last a decent amount of time on this as well. I'd definitely get some goggles if you plan on using this. The beam is bright and can be harmful to your eyes. Here are some questions/answers that I had that I will answer now that I have the laser. Q: How visible is the beam? A: Not very visible to the naked eye. The only time I can see the beam is if I'm looking directly down the line of sight of the beam. Even at night it's the same. Q: How far can you see the laser point? A: At night, I can see the point of the laser almost a mile out. Any farther than that I start to lose it. During the day, I can point it down the street from my house a few houses and still see it, but not much farther than that. Q: Does this laser burn stuff? A: Yes. This was my first burning laser. At first, I just pointed the beam at some wood expecting it to burn, but nothing happened. Once I unscrewed the cap where the laser beam focuses to come to a finer point, that's when I started to see smoke and was able to burn holes into dried leaves and black tape.

I ordered the green laser and a battery to go with it. There were some issues with customs because of shipping the Li-ion battery but I received prompt communication from Sanwu detailing the issue and both arrived faster than I expected for something coming from China (about 2.5 weeks). The quality of the laser build is excellent; it feels very solid. It's incredibly bright even in daytime. I will be a returning customer for one of the more expensive and more powerful lasers in the future. You cannot beat Sanwu for this price. I am an extremely satisfied customer and cannot recommend this company enough.

Ordering is great. Very fast shipping to Canada for Lasers. 11 days to door! That's Canadian Customs and delivery!!! Batteries which are shipped separately take a very long time. Over 60 days...still not received. Green 304 Laser- 5 stars - Great laser! VERY BRIGHT!!! Even in the full sun light. Red 304 Laser- 4 stars - Very Nice ! Can see in sun light but not at long distance. Violet 304 Laser- 2 stars - Only good for indoors! Very weak, not very bright at all. Violet is a big disappointment...

200mW red works perfectly. Yes it is a 303 host but you are paying for the laser itself and not the host.

The laser or cool
