Have owned many spas. Found the marquis 319s to be perfect size for 2. Initial discussion with sales person, claimed it was set for 220V (important to make sure lots of jet power). Later found it to be set up for 120V and could convert to 220V, but had nothing to do with jet power, only effected the heater. Sales person did not know the features the spa came with.
Did not set up the Spa for a while, we checked on possible upgrades. Finally service informed us to just go ahead and set it up. Power was adequate. When we picked up the Spa they didnt have a cover. Told us they would give us a used one and order a new one. We are going on 6 months and still can not get anyone to return calls on our new cover. I Do not recommend purchasing a Spa from Spa Brokers.
Finally contacted Marquis Gary Dietzel from marquiscorp.com, he contacted us the next day and apologized for the delay. He is looking into it.
