Massage Gun Deep Tissue, Handheld Electric Muscle Massager, High Intensity Percussion Massage Device for Pain Relief with 9 Attachments & 30 Speed(Black) by OLsky

202230719 Update:
I recently ordered another of these massage guns and I am sad to say they have redesigned the massage gun. The original gun had a 12 Volt motor running on 3 18650 Lithium cells, wired in series. Now they are using a 5 Volt motor. Unfortunately the 5 volt motor has insufficient torque. Now the 5 volt gun loads up and stalls when I apply any significant amount of massage pressure. Also, the gun is now recharged via a USB C port. And while they include a USB C cable, they did NOT include a 5 volt charger.
To be clear, I am not happy with these changes. And I probably will not be ordering any more of these units.

Original review:
I like the strength of the massage, I can not load down the motor speed no matter how much pressure I use, and I use quite a bit of pressure on my stumps (as life has left me as ‘two-wooden-legged-pirate’ –Arrrr!)

Any way…I like the design of the nose of the gun amd it appears to be able to handle large lateral loading pressures quite well from any angle. Generally I use around 5-10lbs of pressure, but If I am really trying to put a nerve out of its misery, and/or break up the scar tissue from my stumps, I will use around 15-20lbs of pressure.

The battery life Seems ok, I will usually use the gun to for up to 1/2 hour at a time. by the end of 30 minutes of use the battery indicator has dropped from 100%, down to 40%. So far, I have not gone below 40% and as I mentioned I tend to work with pretty hard pressure applied. Also, you will have to reset the motor speed every 5 minutes as the gun has a 5 minute ‘auto off’ bug/feature.

The speed is controlled by a ‘touch screen’ styled interface. It has a speed range of 1-30. The scale seems linear, but keep in mind, muscle tissue doesn’t actually measure motor RPM’s very well. It charges the batteries from a 12 Volt DC 100 mA ‘wall-wart’ which is detachable at the gun end.

My only real complaint is the power switch. The power Switch is a subminiature unsealed slide switch. This is a very low reliability part at the best of times, but putting it on a device that I am often trying to use at night, in the dark, while in a muscle spasm, well, let’s just say, it is a poor choice. I can feel the leaf springs inside the slide switch because the slide lever is fairly tall, so when I am fumbling around in the dark I will often try to switch it the wrong direction (or sideways), and obviously this is hard on the switch mechanism. The power switch is located in a good spot at the butt end of the gun, but the manufacturer should have used a push button styled switch, not a slide switch designed for a 1968 transistor radio.

I expect the power switch will be the first thing to break.

The case is a molded fabric affair that is to hold all the different tip types that the gun comes with, as well as the AC power supply and manual, and of course, the massage gun. Fit and finish are excellent, but I would ahve prefered a grippier surface, as the smoth plastic can sometimes be difficult to hold. But the again I guess that is why theeres is also ‘grip tape’ for sale.

The gun is heavy enough that almost all of the impact force is transferred to the tool tip, with very little resonant reflected oscillation transferred beck to to the gun (thank you mass and inertia laws). The gun is smooth at all speeds, and it is very quiet. If the manufacturer would have suppled this gun with a metal tool tip, l believe you could pound 16 penny nails, or use it as a sabre saw, but i digress toward my hacking tendencies…

Over all I liked this massage gun so well that I immediately bought a second one as a spare, and my wife also bought one. It is going for an amazing range of prices from other mfg.’s but I think they are all coming from the same factory in China, so, yeah.

Historically I have tended to wear out other brands of impact massager, usually within 3-4 months of use, however, This massage gun is built a lot like an electric power drill, The reciprocating bushings appear to handle high lateral loads, the gun stays fairly cool even after 1/2 hour of constant heavy use. That is pretty amazing since it has not only the motor heat and the mechanical friction and pressure heating to dissipate, but also the heat of the rapid discharge of the lithium battery pack. It seems to handle it all very well. I am fairly confident that it will hold up a better than other types I have tried previously.

👉 “Excellent product, very easy to use and with good power. It helps a lot to relax the muscles after exercise and relieves tension in the back and neck. The battery lasts a long time and brings different heads that adapt to different areas of the body. 100% recommended.”

Out of the box, it looks well made but that’s where it ends.
The speed adjustment buttons does not work at all. Even under the slightest amount of pressure the unit stalls out so doesn’t do the job of massaging at all.

The worrying part is, where the massage attachments go in, gets incredible hot and feels like its actually melting the attachments, even after 30 seconds.

works well, plenty of attachments for multiple configurations, good contron, nice and easy to beat you silly. i
have neuropathy in my hands and arms, used it just a little while and noticed better feeling in my hand
and loosening of fore arms. having cramps in my hands, looking forward to seeing how it works on those.
all in all, 2 thumps up!

I’ve been having a sore neck (upper shoulder)for 2 days , I wasn’t able to even sleep how sore it was . Let me tell you how this is worth every penny . As soon as it came home I used it for 8 min and I’m blown away. I have zero knots on my neck anymore . I’m able to lay down and get up with zero pain on my neck . 2 sleepless nights in pain sitting right up not able to lay down . This is a game changer and let’s not forget the price . Very affordable cheaper than getting a massage. I would recommend 10000% .
