Buying a brand name - Streamlight TLR-7 HL-X 1913 Sub USB Multi-Fuel High-Lumen Rail-Mounted Light

Light turns on and functions, but thats just about the only positive thing about it. Feels cheap, the little inserts for different rails wiggle around in their slot like a toddler wearing their dad's boot.The buttons wobble around and are made of a cheap plastic—the two on mine are even different. The left side gives a solid, tactile "click" when pressed, but the right doesn't, so you can tell their parts are not consistent. The screw for the rail clamp sticks out past the body of the light and snags on everything it touches. With issues like these, I have very little confidence this thing will perform when I need it to, or it will endure serious use.
