Well it's been just about a year since we bought our Vanguard. Very, very happy with it. Our friends own an " off the rack" no-name hot tub and we sometimes go over and soak at their place. Our Vanguard is day and night compared with theirs. The quality of the massage, the power of the jets comfort of the seats and the filtration system on the Vanguard can not even compare to theirs. They even say how much better our tub is compared to theirs. I am very glad we went with HS.
The only issues we have had in a year with the Vanguard is the auxiliary control panel (and HS admits that they have had issues with it). The buttons eventually either break off or fall into the panel making it unusable. The tech came buy before the weekend and installed the third panel. HS has found a new manufacturer and have been testing this new panel for about six month without any failures. It is a much better design and looks very sleek and cool, with a purplish blue back light. The buttons are no longer a separate component, but are part of the face of the panel. This should work way better and I do not force any failures with it.
Old:
I'll take a picture of the new one when the rain stops. Unless someone already has a picture and wants to post it. Probably all the new spas come with this new panel.
