Bright for how tiny they are, super easy to mount, very universal and easy to adjust, and the charging port is USB-C, which has a waterproof plug. Not sure how well they do in the rain aka its water resistance, only rode through light rain, which I had no issues with. Have been using them in my ride home from work at night and never charged them, surprised how well the front one lasts considering I keep it on the highest setting too. Battery life seems great. Overall looks, it look like it's part of my bike, not obstructive nor standing out. The back one is red and has a few flashing modes, nice and bright, strong light. Overall for how cheap they are, their quality is great. Ride safe y'all!
