Review on Stay Safe While Cycling With G Keni Smart Bike Tail Light - Auto On/Off, Waterproof, USB Rechargeable, And Ultra Bright LED Warning Back Bicycle Flashlight! by Don Olsen

I was very excited about this product and it worked well the first 7 weeks. It did the job informing drivers behind me of my intention to turn. However it just died abruptly. Return period had ended. No go. expected the product to last a year or more at least then I would have been happy. Seemed to be a quality product but just quit for no apparent reason. Was not abused. Was not left in the weather. No reason I can think of that it just quit.I cannot recommend this product. Not reliable. Will try a different brand by a different manufacturer.
