What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Ekrin B37
One whitelisted tester, Reviewed (USA Today), hands-on tested the original Ekrin B37 and placed it mid-pack: praised for a range of decent speed levels and manageable, non-overpowering noise, but dinged for a top-mounted button that makes one-handed speed changes impossible on the L-shaped handle. (1 sourced review, 1 lab-tested.)
Praised: Decent range of speed levels, each delivering a usable massage; Operating noise stays manageable, not overpowering.
Flagged: Top-mounted button makes one-handed speed changes impossible on the L-shaped handle; Single button only cycles up, so lowering speed means churning through every setting.
