Exactly as described
Assembly took two of us about an hour with a screwdriver, just like they said. Heats up fast and the cedar smells incredible. Freight delivery was smooth.
Best purchase for recovery
I use it almost every day after training. The low-EMF was a big deal for me and the carbon panels heat evenly. Worth every penny.
Great value vs the boutique brands
Shopped Sunlighten and Sun Home first. This was thousands less for genuinely comparable quality. Docked one star only because I wanted more color options.
Plug and play, seriously
Plugged into a normal outlet in the spare room and it just worked. Bluetooth and the chromotherapy lights are a nice touch.
