After a few months of research to avoid wasting more money on niche products that don't do as they say, lack quality, unreliable warranties, I decided to spend a bit more and go for the gold!
This unit is so close to the commercial units at my chiropractor.
It was simple to unbox, setup and start using in under an hour.
Sturdy? Yes, very. It is a bit heavy and thank goodness for what it is capable of doing.
