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.
Sportneer Elite D9
One whitelisted tester, Tom's Guide, produced a verified hands-on review of the Sportneer Elite D9. It rates the gun a strong budget buy: an excellent six-hour battery life that rivals guns nearly five times the price, a wide six-speed range (1300-3200 PPM), and a protective hardshell case with chrome oil-friendly attachments. The trade-offs are a short 11mm amplitude and low stall force, which yield a shallower, less powerful massage than premium Theragun or Hyperice guns, plus a fairly heavy 2.3-lb body. (1 sourced review, 1 lab-tested.)
Praised: Excellent six-hour battery life, unusual at this low price; Wide six-speed range (1300-3200 PPM) versus pricier Theraguns; Protective hardshell case plus chrome oil-friendly attachments.
Flagged: Short 11mm amplitude means a shallower, less powerful massage; Low stall force; motor stalls under moderate pressure; Heavy at 2.3 lbs, tiring on wrists and forearms.
