I have had a hot tub since 1998. At first there were times when it was damn, the sun is coming up.
It has helped a lot when I have had back problems.
It stays ready to use, but I have not been in it in months. No way I would want to get rid of it though.
All the pumps have been replaced a time or 2, and one new cover. The old cover still looked good, it just got too heavy to move.
Honestly, if I did not have pins, I would probably still get in the hot tub almost every night. A big thing also is my girlfriend loves pins, and does not care about the hot tub. Previous girlfriends loved the hot tub so that was where we stayed a lot.
