Ekrin Athletics B37 vs Therabody Theragun Prime (Gen 6)
Which should you buy? Our verdict on both, pulled from our full Best Massage Guns: Percussion Power vs Marketing Hype comparison.
The Ekrin B37 wins on balance: it takes hard pressure without stalling, runs quietly, lasts all week on a charge, and carries a lifetime warranty for a fair mid-tier price. Step up to the Theragun Prime only if its deeper 16mm stroke and reach-everywhere grip matter more to you than battery, noise and value. The Hypervolt 2 is a fine, quiet everyday gun if you find it discounted, and the Theragun Mini is worth it only as a second, travel-only device.
