I needed a new headset after destroying the excellent wired one that came with my phone, so I decided to give this wireless one a try. I got them for my wedding and was able to wear them for ceremony and reception till the end of the party ( I had back up shoes in case if my feet get tired, but did not need them). For the price I paid, it should at least last me, oh, I dont know, a MONTH. They are easy to put on look great and feel wonderful. Definitely would NOT recommend. 5 go with the 8, but if its a 7, go with a 7). It’s easier to put on than to take off. It uses a mounting system similar to my Cateye Volt 700 which allows for very precise and secure mounting to the handlebar. The shoes definitely run bigger, I usually wear a US9 - 91/2 and bought a size 81/2 which fitted well. seems like major programming error that needs an update.
