The RRGFB infrared sauna blanket — sold under model number FUL-8203-NEW — is a heated PU leather blanket measuring 180.34 x 78.74 x 0.66 cm and weighing 6.08 kg. At £159.76 it lands at number nine in this guide, between the £62.62 three-litre tent and the £199.99 six-foot tent, even though its listing publishes no wattage figure at all to set against either of them.

Its own numbers disagree with each other. The listing states 4.2 out of 5 from 33 ratings, but the breakdown underneath that shows 8 one-star, 5 two-star, 6 three-star, 18 four-star and 63 five-star ratings — a total of 100. Thirty-three ratings cannot produce a histogram that adds up to 100. Every figure on this page comes from the Amazon listing as published, not from any test we ran.
