I just received and unboxed my waver today. Signed up for warranty. It’s very sturdy and comfortable to stand on. I love that it shows you where to place your feet. The height is great that it could fit under my bed when not in use.
I've only used the Waver a couple of times but it's pretty fun. My main goal is alleviating lymphedema, so we'll have to see if it works for that. Other goals include improved balance, bone density, muscular pain relief, and weight loss.
