The CatEye AMPP1100 is excellent 👌🏻 I use it most of the time on lowest brightness mode to have the longest runtime and avoid heating up, that's because my ride usually lasts for 5+ hours The CatEye Rapid X2 Kinetic is good but I wish there was an option to disable kinetic option ! It's so sensitive that it turns on without braking. It turns on if the road is not smooth I was using rapid mode and it lasted for total 3 hours then turned off... I am a little bit disappointed but It still a good product... Also the large rubber band didn't suit to mount the light on seatpost , should have been larger. I have installed it on thin tube of the frame. Next time (maybe next year) I am planning to buy CatEye Viz 450 and maybe Volt 1700 if I found good discount on them. I must mention that when I placed my last order I forgot the rear light, contacted CatEye support and they helped me add it with discount! Thank You CatEye ❤️
