Works better than expecting. It’s very very bright green and has a great slim design that fits in your hand or pocket comfortably. It’s fun to use

No actual quantified output power is specified so I figured I'd order a few and see what they did. Long story short, I'm keeping them. It's a powerful little laser for ~$13, but there are some caveats. Pretty much 60-80mW on full charge. They leak a considerable amount of IR out the front, so I had to add a filter to my setup to get a somewhat accurate measurement of the green power. This is fine imo, you shouldn't be shining this laser anywhere near someones eyes anyways. Addition of an IR filter wouldn't really make them all that much safer. At full charge, I got about 65mW for a continuous entire 1 minute on. At 2.5 minutes it dropped to about 40mW and by 5 minutes we were down to 25mW. My guess is it's likely because it's heating up and you're getting less efficiency out of the pump diode. I left it off for a bit a came back and it was right back up to a sustained 65mW. But this is exactly what you should expect out of a handheld laser pointer. Who's sitting there holding it on for a constant 5 minutes? I was actually surprised it was still going at 65mW at the 1 minute mark. The battery isn't accessible (as far as I could tell) without having to rip off an end that would need to be re-glued. So I couldn't get a measurement to try and estimate how long these would last full charge, nor see what the mAh capacity of the installed battery was. The internal LED doesn't line up well with the hole so can be hard to see when its charging. FYI, it turns off when fully charged. The instruction say to use it until the battery is mostly discharged to preserve the life of the battery, but there's no indication of the battery SoC so this is likely difficult to do. 5 stars because it's pretty powerful for 13 bucks.

Works just fine.

We got this for our cats, who naturally have no interest in it. But if you're looking for a good, bright laser pointer for presentations or for pointing out things on a large job site, this is the one. I worked for years in the AV rental industry, and saw many presenters use a crappy red laser pointer that you could barely see on the screen in a ballroom. They should have had this one! It's a monster. It charges easily with a male USB-A connector right inside the base. It's bright as heck, and the dot is larger than most. So even if you're pointing to something at the other side of a large industrial space, everyone's going to see it. It has a removable cap that will give you a trippy "star" effect where the dots move and separate as you turn it, might be cool for DJ's or raves. The quality of it is good, it's metal construction, and it's easy to use and charge.

So worth the money!!! The bright beam is amazing and it will travel FAR! Not bad for a little laser and the build quality is amazing!! Go get yourself one it’s so much fun!!!

Great little laser. Could put a light on a tree at 300 yards. Could not believe it was so bright.

Bought this to use for paranormal investigations and the light is bright and works well. The patterns are nice and work well for what I need to spot anything moving through the area. My only knock, and it's a significant one, is that you must depress the button to keep the light on. You can't just turn it on, like a flashlight, and it stays on. Well, that's a big disappointment as its use will be limited. I decided to keep it due to the price and will have to make due for now. I wish I knew this prior to purchase as I would've looked elsewhere. The description doesn't mention this. Otherwise, it is o.k.
