I was unable to used the hyper shell because of the fact that the original waist strap simply didn’t work fortunately I came a cross the idea Of using a pair of standardsuspenders and that work ok, so when I saw this on your website for fixing the problem I order a pair right away, so I will let you know how they work onceI used them for a while and (hopefully) this will fix the problem of them falling down. I gave your device to my brother who has been unable to walk for any certain amount of time and unfortunately he can do the things that he would like to do like hiking for enjoyment without being in constant pain because of both a knee replacement that hasn’t worked out and a leg brace had really caused him to lose the ability to walk for any length of time. So Iam hoping beyond hope that this device will work to improve his quality of life by allowing him to take small hiking trips near he lives in Northern Washington state, the one problem that I see with this device is that there is a big learning curve for how to use the Hyershell phone app unfortunately it is rather difficult to master and I’m hoping that his wife who is computer savvy will rises to the challenge and hopefully she will help him to master the app. We will see
