OK in some Aspects/ Below Average in Others
OK in some aspects. Odd charging as it can use. Cable. Has to be plugged into a female USB socket and the charger cover is a pain to remove. I’m gonna lose it. The frame adaptor piece is a joke. Blinking light that responds to braking is cool. Hate that they say it has AI. That’s just stupid.

Works but fragile charging method
No, I do not recommend this product
Purchased for the high lumens(300) and good price. I like the multiple modes and memory however to charge it, you must pull the bottom off to reveal a stick, flash drive style. Due to the weight of the light, you can feel the stick loose. Overtime this will render it useless. Poor design. Will keep but won’t buy again.
