x as I would expect for a new product on these times, but there is no difference in use, wireless connection is very reliable. I washed them but didnt trust putting them in the dryer and I suspect they wont survive many washings. I could not send them back as I had walked in them before I found out that they pushed your feet out of them. I found the touch controls took me a few days to get used to, but like anything, once you get the hang of it it becomes simple, much better than press controls! all ok with a simple hose between the holes and a rinse. I bought this to have a little fun recording myself and chatting with my friends online during this wonky time period. I didnt like that because I feel it would get even looser as I lose weight. Add a good book, a cup of tea, and some chocolate and life is very good indeed She is 5ft6in and size uk 10/12, so we ordered a medium. BUT the microphone is way too low.
