  • Super high beam. Small enough to put in purse or deep pocket but with very strong beam. Long lasting batteries. My grandson loved it so much, he wanted another one to have one in car and one in house!

  • The flashlight is very bright compared to ones I've bought in stores and for half the price. I love that it's rechargeable and comes with different cords depending on your charging preferences.

  • So far, this thing is BRIGHT. I'm talking, able-to-see-it-on-a-sunny-day bright. It was also a pleasant surprise to see that it came with a spare battery. I'm taking it camping this weekend, so if I have any problems with it, I will update.
