Yes I have read all the Thermo Spa complaints on the internet.Yes, it is true that they use old parts (I think from a dumpster) to put in the brand new hot tubs.
You should really do your research before buying one. You will be getting ripped off big time. If you buy one it will completely fall apart and leak because of the old parts they put in them. They are ripping people off and should go to jail for bad business practices.
They cannot even supply replacement pumps or parts because they use them for new spas.
Their motto is to "just keep selling them and making thousands" customers won't know they are used parts.
