As soon as I got it I used it and it charges really fast. I love the way these things fit. Chose white color because it looks like original. Picking this speaker took a fairly long while and in the end, I mostly chose it because it became one heck of a good value. I do not like the sound signature, and Ive tried. She is very pleased and loved them. Connectors are plastic and take care when sliding onto poles to prevent cracking. Build quality seems very solid, have worn these in some light rain/snow, and they even took a tumble onto the concrete once, but no issues or scratches as a result. Easy to install and now my bikes are stable when kickstand is down. I previously bought a headset from Vankyo which I really liked but ended up giving it to my son when he broke his own headset.
