They sound great, shipped fast, and even light up and have a radio! I always leave mine at 7. It was peaches and cream until the last connection (the bottom center). Perfect for everything day wear or business casual. Super Crocs :) nach 6 Jahren haben meine alten aufgegeben und brauchte neue. I hope this helps in deciding size, the purchasing decision is a no brainer. That makes the wheel slow down really fast when you stop pedaling a short time, but also makes accelerating real easy. Not a huge fan as assembly difficult. The sound is pretty good while listening to music from my Iphone or watching tv from my 4k apple tv. So if you need it that badly for something like trailrunning (which is what I use the pack for), then perhaps its worth that for you, but I would argue that its more for the competitive market of serious race-runners than simple weekend warriors such as myself.
