Ekrin B37S Review (2026)
A research-based review of the Ekrin B37S: battery life, angled handle, and the lifetime warranty.
Ekrin Athletics B37S
8-hour battery and a lifetime warranty.
Our verdict
The Ekrin B37S is the endurance pick. Its 8-hour battery is roughly double most competitors, the 15-degree angled handle genuinely helps solo users reach their own backs, and the lifetime warranty is unmatched in the category. It is not the most powerful gun here, but for daily users the combination of battery, ergonomics, and warranty is compelling.
What we like
- 8-hour battery, roughly double competitors
- Lifetime warranty, unmatched in category
- 15-degree angled handle for solo back work
What to watch out for
- Larger than mini guns
- Fewer smart features than app-connected rivals
- 56-pound stall force rating is generous on paper
Who it is for
Daily users, physical therapy patients, and anyone who hates charging devices or dealing with warranty claims.
Battery and charging
Eight hours of rated runtime is the standout spec. In practice that means weeks between charges for typical use, which removes the most common annoyance of massage gun ownership. When it finally needs power, standard charging keeps it simple.
Ergonomics
The 15-degree angled handle is a thoughtful touch for the most common solo-use problem: reaching your own mid-back. Combined with six speeds and a 56-pound stall force rating, it handles full-body routines without assistance.
Warranty and value
The lifetime warranty is the real differentiator. Massage guns are mechanical devices with motors that wear; a company willing to back theirs forever is making a meaningful promise that competitors with one-year warranties do not.

Questions, answered
Is the lifetime warranty real?
Yes, Ekrin advertises a lifetime warranty on the B37S covering defects. As with any warranty, keep your proof of purchase and read the terms for exclusions.
Is 8 hours of battery realistic?
That is the manufacturer rating at typical speeds. Real-world use at high speeds will be lower, but it remains roughly double most competitors regardless.
Does the angled handle actually help?
Owner reports suggest it does for solo back work, the use case it was designed for. For arms and legs the angle is neutral.
