thought I was getting a 1000 lumens flashlight, however, it's bright and is far better than any standard flashlight on the market...excellent for seeing whatever you'd like at night and is tactical if needed...
this sucker gets hot when you use it for too long, otherwise great light for the money. Get this now
this light is no joke guys at work all want one one guy went out and spent $200 plus on another stream brand and this little light was brighter than his
this is the best and brightest pocket light i have ever owned it has ruined looking at all flashlights in the store forever almost every light now is a joke compared to this thank you china or where ever you came from.....
this is one of the best lights I have it lasts for a long time  I need to order another one to put in my other truck . highly recommend this light well made
this is a good very bright light for the money. seems to be well made and is easy to use. i purchased  for my home shotgun. i havent yet been able to take it to the range yet to see how it holds up but from what i&#34;ve seen of it i dont believe there shouldn't be any problems considering it not a gun i shoot a lot anyway. it lights up a room very well and is the brightest light ive had shy of spot light. you dont want to be looking into the wrong end of it.
this is a good buy i put it on my ar 15 also got the remote tactical switch but no batteries
this flashlight is the brightest one i own. but the bulb didnt last but bout a month. i upgraded the bulb and have been very happy with it ever since.
recently alot of people at my job got these flashlights so for the money I figured ill get one and test it out. The plus is that these things are bright, very bright. I noticed some people say that the threads are weak when you have to open/close to put the battery in, the threads are somewhat fine and the material that these are made of appears to be aluminum so if you're not careful I could see them getting crossthreaded but if you're careful this isnt really an issue. My main grievance with this light is the fact that whenever you turn it on and then off, it is never on the same setting that you last left it on.
Answer: no
