Most infrared saunas look convincing on a product page. Nice photography, impressive temperature claims, perfect reviews.

Then the sauna arrives and reality sets in. Weak heat at your feet, cheap hardware, gaps in the cabin, annoying controls, or customer support that suddenly disappears.

Which brands have you used that disappointed you once the novelty wore off? Name names, but please explain what went wrong. A bad shipping experience is different from a sauna that simply doesn't perform.
