Who should buy which
Renters, apartment dwellers, and anyone testing the sauna habit before committing to a $4K+ permanent install.
You can install a real infrared cabin (Sun Home, Clearlight) or you need a social/two-person sauna experience.
Buyers who want a credible heritage-brand far-infrared sauna with lifetime heater warranty and the largest service network in the category - and who don't need near or mid infrared in the same cabin.
You want full-spectrum (near + mid + far) in one cabin (move to mPulse), you live in an apartment without 220V access for 2-person+ cabins, or you can't justify $4K+ over a sauna blanket.
