We were immediately impressed by the quality of the Waver. Heavy and sturdy enough to withstand the vibration. Haven't done a real session yet but did briefly try it out without any problems. After reading the instructions I think I am going to do my first couple of sessions sitting (in my 70's), just to get the feel of machine and become familiar with the remote. Looking forward to not aching so much.
This product seems to be built to last. It is very sturdy. It holds my frame and I am a very big guy. I have only had it for 2 days so I am still learning all the benefits it can offer.
