So far, so good! It was very easy to unpackage, move into place, and setup. We love it is lightweight enough to move to another location later if we decide to. It took about 24 hours to heat up, starting with 44-degree water, for those wondering - and we've used it every night since. Having four people in here would be possible, though definitely cozy. I'd suggest this "4-person" tub is more suited to two people.
