Top complaints
Kyota Genki M380
- Heat is hit or miss
Wirecutter's testers were mixed: some found the warming just right, others too hot or hard to adjust.
Source: Wirecutter - Remote-only controls
There's no touchscreen. Because it uses a handheld remote, you may have to pull your arms out of the arm massagers to change programs or settings (Wirecutter).
Source: Wirecutter - Few frills for the list price
Wirecutter says it usually retails for $7,000 (often on sale for $4,000) yet lacks some bells and whistles. Its buying links showed $2,799 at Amazon and $6,715 at Home Depot.

Osaki OS-3D Champ II
- Auto programs can be too intense
Amazon owners say even the 'gentle' mode is quite aggressive and deep, that they felt a little bruised after day one, and that intensity can only be reduced in manual mode. An 81-year-old reviewer found most programs too rough, and another described the rollers suddenly jumping to maximum.
- Knocking noises and software glitches
Amazon's review summary says some owners report loud knocking noises. A 1-star reviewer says that after 10 months of daily use it began knocking, locking up mid-recline and shutting down. A 3-star reviewer lists bugs: an airbag section not activating, Bluetooth staying connected after power-off, and legs retracting fully in zero gravity.
- Shorter coverage than the ads suggest
Good Housekeeping lists no calf kneading as its con. An Amazon reviewer says the SL-track stops well short of the hamstrings and barely reaches the glutes. Another notes the body scan isn't saved, so it repeats every session.
