Crtch Bike Tail Light Ultra Bright Bicycle Laser Rear Light - Cycling Projector Safety Warning Lamp- Water Resistant- Back Flashlight for Mountain Bike- 2 Laser 5 LEDs

1) Back panel broke off (into soft grass in a field) after first 12 hours. I used steel wire from home depot to attach it after that to keep testing.2) On/Off button stopped working after 22 days. Must not be water resistant or something, and being that on day 2 onward I duct taped it's back side to ensure its' water proof, thus must be somewhere in front.3) The laser only works when mud doesn't fling up from tires, really horrible ergonometrics. Why anyone would be so dum as to put lasers behind an embedded concave surface pointing down, leave it to Mainland China for this one. Even q-tips can't fully clean the mud out of the sharp embedded crevice. GUYS NEXT MODEL PLEASE REMEMBER PEOPLE NEED A PROTRUDING SURFACE, NOT CONCAVE SURFACE TO PUT LASERS BEHIND.

Dead On Arrival. Tried new batteries, checked contacts... nothing. Item is just a chunk of plastic. Too light to even be a door stop. Trash. DO NOT ORDER. Neat idea though... if it worked.

The bar clamp is made of low quality plastic which easily breaks

The laser is really dim and barely seen in a dark room on smooth concrete. The flashing LED's work well though which is why I gave it a 3 star, otherwise it would have been 1 star.The mount was too big to fit the seat post, even with the two rubber pads inside. I ended up taking off the round seat mount portion of the mount and mounting it on the front of the bike on an existing bracket.

The unit arrived on time and in good condition. I had to make my own attachment bracket since the unit only comes with a bracket to attach to seat post. The unit worked as advertised and the bottons and lasers worked well. The only issue I had was that it was difficult to obtain the desired pattern on the ground, no matter what position I oriented the device. When I finally got the lines to be parallel, the little bicycle emblem was squished and difficult to recognize. Despite all of this everyone loves the device and all my neighbors want to get one. I was the first on the block to get one!

Cheap plastic. Lit bike lane does not appear as in picture. Not worth the money.

Very pleased with the light. The only shortcoming I have found is that if you have an under the seat tool pouch it is almost impossible to position the light so it can fully create the image it is intended to behind you. Very happy though and would order again
