The sauna was shipped very quickly. I did receive with hidden damage. The glass door was broken. After a week the replacement door was received. I had to live with the heavily scratched door panel from all the broken glass as the factory would only replace the door.
I do love the spa. It was a straight forward assembly with no problems. In my opinion it is sturdy once completely assembled. The floor was sturdy after installing the heating panel.
The Bluetooth stereo works really good. Paired with my iPhone quickly and sounded good. I did have a problem with it getting hot and shutting off. I put a thin piece of insulation board with aluminum facing the interior of the sauna to reflect heat away from unit on the bottom and sidewalls of the wood housing making sure not to impede the top vent holes. I have had no more problems.
The lights work very well. Two exterior lights that have adjustable angles. It has one interior panel with alternating light colors.
My wife and myself used the unit last night. The temperature surrounding the sauna was 65 degrees. It took 35 minutes to reach 150 degrees. After reaching the set temperature the heating will cutoff until it drops 2 degrees and then restore the heat to reach the set temperature. It has an adjustable time with a 60 minute top time. If you preheat you can raise the time back to 60 minutes after entering.
To this point, we love the sauna. It looks very nice and well made. I would buy it again. My only recommendation would be to tear down the pallet before signing and make sure there is no damage. In my case everything looked good externally, but had the concealed broken door.
I think at this price point being able to achieve 150 degrees and the quality it would be hard to beat.
