Quick Answer: The Ekrin Kestrel is Ekrin Athletics’ flagship massage gun for 2026, priced at $349.99 with a 13mm amplitude, 55+ lb of stall force, and six speeds from 1,800 to 3,500 RPM — the deepest reach and widest speed range in Ekrin’s five-gun lineup. It undercuts the Theragun Pro Gen 5 at $529.99 by $180 while landing in the same stall-force class, and it carries Ekrin’s lifetime warranty, which neither Theragun nor Hyperice offers at any price. Massage Gun Advice called it a potential “massage gun unicorn” for pairing near-Theragun-Pro output with USB-C charging and up to six hours of battery life.

Ekrin’s B37 built the brand’s reputation on stall force and a lifetime warranty at a mid-range price. The Kestrel takes that same formula and pushes it to the top of the lineup: a deeper stroke, a wider speed range, and a “tower” grip designed for angles the B37 can’t reach comfortably. Here’s the honest breakdown of what the Kestrel gets right, where it still trails a Theragun, and who should buy it over the B37.

What the Ekrin Kestrel gets right
The deepest stroke in Ekrin’s lineup. At 13mm, the Kestrel out-reaches the B37 and B37S (both 12mm) by a full millimeter — the difference between working the surface of a muscle and actually digging into it on dense tissue like glutes or hamstrings. It’s one of only a handful of guns on the market to clear 13mm at any price.
Six speeds, the widest range Ekrin offers. From 1,800 to 3,500 RPM, the Kestrel adds a top-end setting none of Ekrin’s other four guns reach, giving more headroom for warm-up-to-deep-tissue transitions in a single session.
The “tower” grip solves a real angle problem. On top of the usual 15-degree angled handle, the Kestrel’s body is shaped so it can be held vertically like a column — Massage Gun Advice singled this out as making mid-back and hamstring work far less of a contortion than a standard pistol grip.
Lifetime warranty, same as every Ekrin gun. Register within 30 days of purchase on Ekrin’s site and the Kestrel is covered for life, plus a 30-day money-back guarantee. Theragun and Hyperice both cap coverage at one year — motors and batteries are the parts most likely to fail by year two or three, so warranty length that outlasts them is worth real money.
Where the Ekrin Kestrel falls short
Still short of Theragun’s deepest stroke. The Theragun Pro Gen 5’s published 16mm amplitude beats the Kestrel’s 13mm by 3mm — meaningful for anyone who weighs stroke depth above all else.
$120 more than the B37 for a 1mm/one-speed upgrade. The Ekrin B37 matches the Kestrel’s warranty and comes within a millimeter of its amplitude for $229.99 — most buyers won’t need the Kestrel’s extra reach.
No app or connected data. Like the rest of the Ekrin lineup, the Kestrel is a manual-control device with no companion app, guided routines, or usage tracking — a gap against Theragun’s ecosystem for buyers who want that layer.
Ekrin Kestrel vs the alternatives
| Massage gun | Best for | Amplitude | Stall force | Price |
|---|---|---|---|---|
| Ekrin Kestrel | Deepest reach + warranty | 13mm | 55+ lb | $349.99 |
| Ekrin B37 | Best value / warranty | 12mm | 56 lb | $229.99 |
| Theragun Pro Gen 5 | Deepest amplitude overall | 16mm | ~60 lb | $529.99 |
| Hypervolt 3 Pro | Quietest flagship | Not published | 70 lb (published) | $349 |
- Kestrel vs Ekrin B37: the real decision for most Ekrin shoppers — $120 buys 1mm more amplitude, a sixth speed, and the tower grip, not a different warranty or a different brand.
- Kestrel vs Theragun Pro Gen 5: the Theragun’s 16mm published amplitude still wins on raw stroke depth, but the Kestrel matches it closer on stall force for $180 less and adds the lifetime warranty Theragun doesn’t offer.
- Kestrel vs Hypervolt 3 Pro: near-identical pricing ($349.99 vs $349), but the two guns win on different specs — Hypervolt’s published 70 lb stall force is the highest of the four, while the Kestrel’s 13mm amplitude and lifetime warranty are the trade Ekrin buyers are making.

Who should buy the Ekrin Kestrel?
Buy it if: you regularly work dense tissue like glutes or hamstrings, want the deepest stroke Ekrin sells, and value a lifetime warranty over shaving $120-300 off the purchase price.
Skip it if: you don’t need the extra millimeter of depth over the Ekrin B37 (save $120), or stroke depth above everything else matters most, in which case the Theragun Pro Gen 5 still wins on paper at 16mm.

The bottom line
The Ekrin Kestrel is the deepest-reaching, widest-speed-range gun Ekrin has ever built — a 13mm amplitude, 55+ lb stall force, and six speeds up to 3,500 RPM for $349.99, backed by the same lifetime warranty as every other Ekrin gun. It still gives up 3mm of amplitude to the Theragun Pro Gen 5, and most buyers will do just as well with the B37 for $120 less, but for deep-tissue devotees who want Ekrin’s warranty at its most capable, the Kestrel is the pick.
