Massage gun comparison
Is a budget massage gun worth it?
Renpho makes some of the most affordable massage guns available. Price is only part of the story: what you feel comes down to how far the head travels and how hard you can press before the motor gives out.
Lifetime warranty
Every Ekrin massage gun is covered for life. Most competitors cover one year.
Longer battery
Up to 8 hours on B37 and Kestrel, and up to 6 hours on Bantam, with USB-C charging.
Quiet brushless motors
Rated at 35 to 55 dB on B37 and Kestrel, quiet enough for the office or the couch.
HSA/FSA eligible
Pay with pre-tax health dollars. Free US shipping over $75 and 30-day returns.
What makes a massage gun feel strong
Stroke length
How far the head travels with each hit. A longer stroke reaches deeper into the muscle. Very short strokes feel more like vibration than massage.
Stall force
How hard you can press before the motor slows or stops. Low stall force means the gun gives out right when you lean in on a tight spot.
Full-size
Ekrin B37 vs Renpho Power+ Thermacool

B37 matches the Power+ on stroke length and stall force, then adds twice the rated battery life and a lifetime warranty.
| Ekrin B37 | Renpho Power+ Thermacool | |
|---|---|---|
| List price | $249.99 | $129.99 |
| Stroke length | 12mm | 12mm |

Where Renpho Power+ stands out: a much lower price, a slightly lighter body, and a head that heats and cools.
Compact
Ekrin Bantam vs Renpho Mini Thermal

Both fit in a gym bag, but they are different tools. Mini Thermal's 6mm stroke is closer to a vibrating massager. Bantam's 10mm stroke and 35 lb stall force give you real percussive massage in a 1.1 lb body.
