Ekrin 365 Review 2026: The Everyday Gun With a Pressure Gauge, Not More Power

Quick Answer: The Ekrin 365 is Ekrin Athletics’ newest and most beginner-friendly massage gun, priced at $179.99 with a 40 lb stall force, a 12mm amplitude, 4 speeds from 2,000-3,200 RPM, and a 5+ hour USB-C battery in a 1.7 lb body. Its standout feature is a Reactive Force Sensor that shows how hard you’re pressing — a genuinely useful safeguard against the most common first-time mistake — but it trades away stall force to get there: 40 lb versus the Ekrin B37’s 56 lb, per Ekrin’s own published specs. It still carries the same lifetime warranty as the rest of Ekrin’s lineup, which neither Theragun nor Hyperice matches at any price.

Ekrin built its reputation on the B37’s raw stall-force-per-dollar. The 365 is a different pitch entirely: instead of chasing a bigger number, it’s the first gun in the lineup built around a sensor that tells you when you’re using too much of the power you already have. That’s a real, useful idea — but it also means the 365 is Ekrin’s lightest-touch gun, not its strongest, and the name (“365,” for everyday use) undersells how different its personality is from the B37 most reviews still point to first.

Ekrin 365 at a glance

What the Ekrin 365 gets right

The Reactive Force Sensor actually solves a real problem. Pressing too hard, too fast, on a fresh muscle is the single most common mistake first-time percussion-gun buyers make — it’s why nearly every guide on this site (including our own how to use a massage gun) leads with “start light.” The 365 is the only gun in Ekrin’s five-model lineup that gives you live feedback on exactly how hard you’re pressing, instead of leaving you to guess. It doesn’t make the gun more powerful — it makes the power you already have easier to use correctly.

Locking attachments you’ll actually keep track of. The 365’s four heads click into place rather than friction-fitting, per Ekrin’s product specs — a small detail, but one you notice the first time a friction-fit head works loose mid-session on a cheaper gun.

A genuinely long battery. 5+ hours from USB-C charging, per Ekrin’s specs — close to the B37’s 5-6 hours, even though the 365’s real advantage over the B37 is grip thickness rather than weight (the two guns are within a few ounces of each other).

The same lifetime warranty as Ekrin’s flagship. Register within 30 days and the 365 is covered for life, plus a 30-day money-back guarantee — identical coverage to the $229.99 B37, on a gun that costs $50 less.

Where the Ekrin 365 falls short

Less stall force than Ekrin’s own cheaper-by-comparison flagship. At 40 lb, the 365 gives up 16 lb of stall force versus the B37’s 56 lb, per Ekrin’s published specs for both models — despite the 365 being the newer product. If you’re working dense muscle (glutes, quads, upper back) rather than doing light daily maintenance, that gap is noticeable.

Four speeds, not five or six. The B37 offers five speeds and the Kestrel six; the 365’s 2,000-3,200 RPM range is narrower at both ends, which limits how gentle or how aggressive you can go.

Not the deepest stroke in the lineup. Its 12mm amplitude matches the B37 but trails the Kestrel’s 13mm — for buyers chasing maximum stroke length, neither Ekrin model beats the Theragun Pro’s 16mm.

Ekrin 365 vs the rest of the lineup

• 365 vs Ekrin B37: the B37 costs $50 more but delivers 40% more stall force at the same 12mm amplitude — the better buy for deep-tissue work. The 365 wins on the Reactive Force Sensor and a slightly more everyday-friendly grip.
• 365 vs Ekrin Bantam: the Bantam is smaller (1.1 lb vs 1.7 lb) and cheaper ($149.99), aimed purely at travel; the 365 has more stall force (40 lb vs 35 lb) and the pressure sensor, but is bulkier to pack.
• 365 vs Theragun Prime: the Prime costs $150 more and matches the 365’s 12mm amplitude, but Therabody doesn’t publish a stall-force figure to compare directly — and the 365’s lifetime warranty beats Theragun’s 1-year coverage regardless.

Who should buy the Ekrin 365?

Buy it if: you’re a first-time massage-gun buyer who wants a built-in check against pressing too hard, you value a lifetime warranty over raw stall force, or you want Ekrin’s build quality at $50 less than the B37.

Skip it if: you regularly work dense muscle groups and need real stall force — get the B37 instead — or you want the deepest possible stroke, which the Kestrel or Theragun Pro still owns.

Ekrin 365 by the numbers

The bottom line

The Ekrin 365 isn’t trying to out-muscle the B37 — at 40 lb stall force versus the B37’s 56 lb, it’s clearly the gentler, more beginner-oriented gun in Ekrin’s lineup, even though it’s the newest and $50 cheaper. What it adds instead is a Reactive Force Sensor that solves a real problem (pressing too hard on a fresh muscle) that every other gun in the category just leaves you to guess at, plus the same lifetime warranty Ekrin backs its whole range with. For everyday recovery and first-time buyers, that trade makes sense; for dense-muscle deep work, step up to the B37.
