The sound quality is absolutely gourgeous! I agree with most of the critical reviews on this mouse. Probably not a problem if the handlebar wasnt tapered or if I use some kind of rubber insert between the mount and the handlebar to give it more grip. Pairs well with almost any outfit! They were the main problem. When battery is low, it repeats audibly, "battery low", every 30 seconds or so, until it dies. Awesome price. 75. Ive had to share the link with friends; everyone loves it. While the overall quality seems to be very good I am very disappointed by the fact that the hose when extended is actually only 7 feet long !
