We love the hot tub.  It’s big enough for us but fits well on our screened porch.  Very good jets and the lower voltage is fine - we have a 220 outlet available but for now don’t see any need to convert.  
Two hitches with instillation.  One of the screws on the panel had been installed at an extreme angle and it was impossible to get to the screw head and remove normally.  Secondly the drain valve was hard to find.  The instructions said it would be n the bottom area, but we finally found it tucked up at the top of the tub. We called Left a number and wrote for help and weeks later still have heard nothing.  So customer service seems to be a zero at this time.  We like the tub so we only took one star off for that, but it’s a gamble if you get a dud - no idea how you would contact them or send it back.
