I have one and take and 1-2hrs bath in it every night while i read or do puzzles. It warms and massages me all over. Mine has an inline heater but it's set at 105 degrees and can't be adjusted...that's too hot for me so I unplugged it. If you buy one, get an inline heater and make sure it can be set for the temp you want. In my last house I had a double one and I think the brand was White Rain. The inline heater I had with that one was really great and I liked that whirlpool more than the one in my new house. This tub is a Kohler.
