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.
Bob and Brad C2
Only one whitelisted tester, Garage Gym Reviews, reviewed the base Bob and Brad C2. It calls the gun compact, quiet, sleek, and effective for most users, while flagging low ~8mm amplitude and merely 'okay' stall force for deep-tissue work. No independently lab-measured numbers were published (its listed specs appear manufacturer-stated), and no second whitelisted source covered this exact model, so cross-source verification is unavailable. (1 sourced review.)
Praised: Compact, quiet, and sleek; Powerful and very effective for most users; Five interchangeable heads, lightweight at 1.5 lb, USB-C charging.
Flagged: Low ~8mm amplitude falls short for deep-tissue needs; Stall force only 'just okay'; Non-angled handle uncomfortable for some; 2000 RPM lowest speed feels intense.
