The heater is perfect; the controller app took a little patience to learn. Once set, it's effortless. Support's reply to my setup question was fast and clear.
This single piece made the sauna feel high-end. Even heat, gorgeous finish, and a smooth purchase from start to finish. Shipping was prompt and damage-free.
I bought it for the look and stayed for the heat. The steam is soft and the column holds temperature long after shutoff. Delivery hit the promised window exactly.
Guests assume it's some designer art object until I tell them it heats the room. Soft steam, fast warm-up, faultless so far. Sauna Co. kept me posted the whole way.
No complaints on the unit — gorgeous and strong. Just plan for the separate controller and proper electrical. The listing was clear and support confirmed my breaker before shipping.
Against light wood the matte black CORE looks like a piece of modern sculpture. And it heats my room evenly without a hint of strain. Sauna Co. shipped it well-protected and the controller arrived in the same crate, as promised.
Silent operation and heat that climbs the walls evenly. The black housing hides nicely yet still draws compliments. Communication from the shop was excellent.
Researched for weeks and nothing matched the CORE's clean lines. The performance backs up the looks completely. Arrived on time, packed like glass.
