He's reviewed every portable sauna on YouTube. He chose ours.

David Maus Jr. has reviewed more portable saunas than anyone on YouTube. (He claims to be the first person to ever do it.) He's selective about what he covers. He turned down brands. And when he does review something, he says exactly what he thinks.

He reviewed the All Day Sauna Co. six-person Deluxe Outdoor Sauna.

Here's what he said:

"There's a ton of sauna brands out there making portable saunas. They are not all created equal. There's a reason I'm very choosy on the ones I actually review."

"This is a well-built sauna. Well built."

"I don't think there's much out there that really beats the bang for the buck."

On the hats: "Out of all the sauna hats I've seen — and I've bought a lot of them — nobody has them that fit just right." Then he put ours on. "Their quality is better and they're obviously a lot cooler."
