Who should buy which
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.
Renters, apartment-dwellers, travelers, and first-time sauna buyers who want consistent full-spectrum infrared sessions without the price, install, and permanence of a cabin.
You want the enveloping, head-in, 180F-plus cabin experience, a multi-person sauna, or a permanent showpiece. Then a Clearlight or Sunlighten cabin is worth the spend.
