Review on Homedics Perfect Temp Travel Massage Cushion: 6-Motor Vibration Massage with Targeted Heating, Cooling, and Zone Control (TA-VC275H) by Rich Fiedler

Haven't tried the heating yet but the vibration and cooling worked very well. Unfortunately, this device only works for a short time before automatically shutting down. I didn't time it, I think 15-20 minutes. I only took off one star because I suspect that virtually every other comparable product has this annoying "feature". This appears to be something the company's legal team suggested, or perhaps a poorly thought-out federal mandate. If you agree, this is an amazingly efficient device. I was really surprised how well the cooling function works. just as efficient as the best ventilated seats I've ever seen in a car. The vibration massage also has a comfortable feeling. My back felt noticeably more relaxed after the application.
