So the good....it works quite well. The temperature does fluctuate a bit, but for the most part it stays within a few degrees of the desired temp. Assembly was pretty easy. (I was able to do it by myself, but I would definitely recommend 2 people). It looks and smells rather nice.

The bad...It is only a 2 person sauna if both people are quite small. I'm not a small guy (6'2", 230lbs) so 2 of me definitely wouldn't fit. My wife is on the smallish side, and she doesn't fit with me. So that's a bummer.
The only other bad part is that the red light isn't really the therapeutic kind. It's just a red light; more for mood or aesthetic. That wasn't clear in the listing and disappointing to discover.
Overall though, I would say it is a great buy at this price point.

No complaints!

We are very happy. The ordering, delivery, and set-up all went smoothly.
For the price, the sauna heats up quickly and everyone in our home uses it. The sauna has come through (as advertised) with flying colors!

The installation instructions are terrible.

Easy to assemble, looks great and love the sauna experience!
