I would start limping a bit about halfway into the day before, now i can be on my feet 8-12 hours and still have no limp and the pain in lowered to just a slight annoyance. And when I come to upgrade my phone in the next year, the holder can be used with the new phone too. Not happy with the sizes as the sizes are smaller than normal. Over all not a bad purchase. _________I?m ambivalent. If you?re looking to shed water weight get this now! Caused severe damaged to expensive bikes. He was very rough on these and used them both wired, wireless, while charging. I use both Barbell row AND T-bar row to maximize my gains! Sony said it was a problem with my brand new mesh network- not really sure.
