Welcome to our forum.
We wet tested the optima first and the jets almost flayed the skin off of my wife's back. Within 3 minutes our backs were numb. ... My wife sat in the center of the tub trying to escape the "therapy". The sundance dealer spent a good 10 minutes bashing the moto massage and telling us what to look for that was lacking like... having to turn slightly from side to side to get a fuller back massage. 3) The "move left and right" is a non-issue. We did it on the optima to try and more evenly distribute the pain. We did it on the grandee to better distribute the massage.
I do not understand these comments on the Optima being overpowered. Â I own one and every seat and every jet have endless adjustments for water control/pressure. Â The jets themselves can be dialed up or down by turning the rings, some jets can have direction changed, diverters can turn seats on, off or adjust it anywhere inbetween. Â I've never left my tub with red, itchy skin or numbness or skin flayed off. Â
