Welcome to our forum.
Royal does not use computer controls. The controls are mechanical.
When it comes to the "pink panther" insulation that is stuffed into "garbage bags", I can't say that your observation and subsequent opinion is wrong any more than I can say that Royal is "right" for constructing a hot tub with this style of insulation. Unless a study is performed probably nobody on this forum can say for sure which style of insulation is better.
Sorry I can't agree with you. Â I think Royal Spas are one of the cheapest made spas around. Â I didn't like one thing about them. Â The insulation was a JOKE! Â I mean who the heck takes a bunch of pink panther house insulation in garbage bags and stuffs it in the cabinet and calls it insulated! Â I couldn't belive it. Â I mean that alone was enough for me. The control by the filters what ever it was for was screwed in and the screws were rusting. Â The tubs just plain and simple look cheap! I am not one that bashes tubs but these are bad. Â Perhaps it was just this dealer (lets hope so). Â But after seeing that I wouldn't even consider a Royal Spa. Â
