Cheap expendable light, compact, light, reasonably bright and waterproof. I have a few and mostly happy with them as I carry amd use them in wet and dirty conditions. Beam is narrow ("bull's eye") which doesn't make a lot of sence; beam throw is still not that great so would be better off with a wide flooding beam for close distance. Also o-ring could be better, they evemtually let moisture in and electric contacts corrode. Overall, pretty good light to carry at work when you need a bit of light sometimes and at this price, if something happens to it, you'll just go get another one, abuse away!

the picture shows 30 Lumens but the product says 50 lumens so its brighter than I expected which was a nice surprise. it's small enough to fit in the palm of my hand, its waterproof and floats just like its says.
