First I liked the ease of unboxing the bike speaker. Almost everything was cardboard and there was no tape involved. It took under a minute to have all the parts ready to go. The written guide is pretty good in English and helped me get things hooked up. Syncing my iPhone in Bluetooth was quick and easy. The 2 LED lights were very bright. The speakers were just too loud for testing inside and did distort a bit at the very loudest settings, but that sound level is way too loud to use on a bike for me. I have an iPhone 8 Plus with a case and cover and it barely fit width wise in the clamping holder. Without the phone case it was easier to mount. I tested calling and answering phone calls and that went fine. However the microphone made the listener have a hard time understanding me. The AUX function was fine and worked well with my MP3 player using a dual ended headphone cable. One cool thing I liked was that there is a micro usb cable included with a Velcro horn button. That’s one loud horn! Another cool find was that the 2 handlebar clamps would work and tighten down on my Giant brand bike that has a handlebar that gets bigger closer to the frame. A different light I own just won’t clamp down. Overall I am very happy with this purchase.
