Ekrin B37v2 Review
The B37v2 pairs a brushless motor and a 1400 to 3200 RPM range with a 15 degree angled handle and an eight hour battery, which is more usable runtime than anything premium in this list and a real answer to the reach problem. Buy it if you want the treatment without the brand premium. Skip it only if you specifically want app-guided routines or a heated head, neither of which changes what percussion does.
Eight hours of battery, a 15 degree handle and quiet operation, for a third less than the premium names.

What it does well
- Eight hours of battery is not a specification you notice until you own a gun that needs charging every week.
- USB-C charging means the cable you already carry works, which no premium competitor in this list offers.
- The 15 degree angled handle addresses the same self-treatment reach problem the Theragun triangle does, more subtly and for less money.
- 1400 RPM at the low end is genuinely gentle, and low settings are where most people should start.
- Locking attachments do not fly off mid-session, which sounds obvious and is not universal.
Where it falls short
- No app, no guided routines, no connectivity. If you do not know how to use a massage gun, nothing here teaches you.
- A smaller brand with less retail presence, which matters most if you need warranty support.
- The evidence for percussion is the same modest one regardless of price: short-term range of motion and perceived soreness, nothing structural.
- Fewer attachments than the premium sets, though four covers the practical range.
- It is not the quietest gun available, only quiet for the price.
What owners report
Published owner reviews of the B37v2 read like the reviews of a product that is quietly good at its job. Battery life comes up constantly, the angled handle gets credited for making self-treatment easier, and the price to performance ratio is the recurring theme. There is very little in the reviews about it failing to do the thing a massage gun does, which is the most useful signal at this price.
The honest way to frame this purchase is that percussion is percussion. The research supports short-term improvements in range of motion and reductions in perceived soreness, and it does not support scar tissue breakdown, fascia release or lactic acid clearance, whatever any brand's marketing says. Since the underlying treatment is the same, what you are choosing between is handle shape, noise, battery and support. On battery this wins outright; on handle it is a genuine third option; on noise it is good rather than best; on support it is behind the big names. Our are massage guns worth it page and specs chart cover the evidence and the numbers.
Against the premium options, our Theragun versus Hypervolt comparison covers those two, and our Theragun Prime review and Hypervolt 3 Pro review cover each in detail. If you are still deciding whether a gun is the right tool at all, foam rolling versus massage gun, massage gun versus massage ball and TENS unit versus massage gun are the comparisons worth reading first, and the roundup covers the field.
Use it on muscle only. Keep it off bone, joints, the front of the neck, the kidneys, varicose veins, numb areas and acute injuries. If you are on blood thinners, or have a clotting disorder, osteoporosis, a recent fracture, nerve damage, or are pregnant, talk to your doctor before using a percussion device. Sharp pain means stop, and pain that persists means see someone.
Who it suits
- Most people buying their first serious massage gun, where this is the sensible amount to spend.
- Anyone who resents charging devices, since eight hours and USB-C is a genuine convenience.
- People who want help reaching their own back without committing to the triangle handle.
Who should skip it
- Anyone who wants app-guided routines and would actually follow them.
- Buyers who need the deepest warranty and support network behind their purchase.
- People treating a specific injury, who should be getting advice rather than buying a device.
Alternatives worth considering

~$320
The triangle handle is the most effective solution to self-treating your own back and shoulders, if that is your main use and the extra $95 is acceptable.

~$349
Notably quieter with six speeds and app routines. Worth it if you will use it in a shared room or want guidance on what to do with it.

Under half the price with heated and cooled heads. Build and battery are a step down, but it delivers the same basic percussion.

Frequently asked questions
Is an expensive massage gun better than a cheap one?
Not for the treatment itself. Percussion is percussion, and the outcomes that are supported by research do not scale with price. What money buys is quieter operation, better build, longer battery, more thoughtful handles and better support. A mid-priced gun that you actually use is a better purchase than a premium one that annoys you.
What RPM range do I need on a massage gun?
A range that goes low as well as high matters more than a high top speed. Most people should start on gentle settings, and a gun whose slowest speed is still aggressive is unpleasant on sensitive areas. Ekrin's 1400 RPM low end is genuinely usable, and the 3200 RPM top end is plenty for large muscle groups.
How does the angled handle compare with Theragun's triangle?
Both address the same problem, which is applying pressure to your own back and shoulders without straining your wrist. The triangle is the more dramatic solution and some people love it; the 15 degree angle is subtler and feels more like a conventional gun. Grip preference is personal enough that neither is objectively right.
Do I need attachments beyond the standard ball?
Not many. A standard ball for large muscles, a dampener for bony areas and something smaller for specific spots covers almost everything most people do. Large attachment sets look generous and mostly stay in the case. Four locking attachments, as here, is a practical number.
Is it safe to use a massage gun every day?
For most people, on muscle, in short applications, yes. Keep it off bone, joints, the front of the neck, the kidneys, varicose veins and numb areas, and off any acute injury. Check with your doctor first if you take blood thinners or have a clotting disorder, osteoporosis, a recent fracture, nerve damage, or if you are pregnant.
