Bests & Worsts Reviews from Amazon

I bought these based on the YouTube commercial. It showed this thing being run over by a truck and being able to use it in emergency to start a camp fire. VERY disappointed. First - No documentation. No instructions. No guide. No specification sheet. No warranty. Second - It's not bright enough or strong enough to warm your hands on a cold night. Third - it came with no batteries. Seriously - NO BATTERIES. Lastly, if you wanted to use it to "blind an attacker" as they claim, you better ask the attacker to wait while you press the button 6 to 10 times to get the brightness or strobe effect you need to blind them. Not as advertised.
