I have a Hotshot SL 50 (older model) that was a road find, I love it, and if I lost it I would pay to replace it. SUPER bright, although I guess the 150 is 3x as bright? And I love the USB charging, although I'm a little at a loss as to how to know when it needs charging.
Once I left it on the floor to charge on a powerstrip, and somebody stepped on it and the circular glass "lens" came out. I just superglued it back in, it's been fine.
