Massage guns come with a wall of specs: amplitude, stall force, percussions per minute, battery hours, decibels. Most of it sounds impressive and tells you almost nothing. Only a few of those numbers change how the tool feels, or whether you'll still reach for it in a month.
Amplitude: how deep it reaches
Amplitude is how far the head travels back and forth, usually 10 to 16 millimeters. A longer stroke reaches deeper into thick muscle like your quads and glutes. A shorter one stays gentler and does better on smaller areas. For everyday recovery on legs, back, and shoulders, somewhere around 12 millimeters is a comfortable middle ground.
Does it stall when you lean in?
Stall force is how hard you can press before the motor stalls out. A cheap gun gives up the second you lean into a tight spot, which is the exact moment you want it to keep going. You don't need a professional-grade number, but a gun that quits under light pressure gets frustrating fast.
You don't need twenty speeds
You'll see guns advertising twenty speeds and eight attachments. In real use you'll settle on two or three speeds and two heads: the round ball for big muscles, and the fork or flat head for specific spots. More options don't hurt, but don't pay extra for numbers you'll never touch.
Weight and noise are why people quit
A massage gun only helps if you actually use it. A heavy one gets tiring to hold against your own back and shoulders, and a loud one is annoying enough that you skip it. If you can, hold it before you buy, or at least read what real owners say about the weight and the sound. These two boring details decide whether you keep using it or shove it out of sight.
Battery and charging
Most guns run a couple of hours per charge, which is plenty when a session only lasts a few minutes. USB-C charging beats a proprietary plug you'll eventually lose. Battery life is rarely what lets you down, so don't put much weight on it.
Is a gun even the right first buy?
Worth asking before you spend anything. A foam roller costs less, covers bigger muscles in one pass, and is harder to misuse, which is why a lot of people start there. A gun wins on convenience and on spots a roller can't reach well. We walk through the trade-off in massage gun vs foam roller, including when owning both actually makes sense.
What we built the Treisa gun around
Our percussion massage gun was picked for the balance most people need: enough amplitude and stall force to work into tight muscle without quitting, and a weight you can hold against your own back and shoulders. It comes with a small set of heads that cover the jobs you'll really do, not a case full of ones you won't. You can see it next to our other deep-tissue tools in the percussion and deep tissue collection.
The short version
If you forget everything else: make sure it doesn't stall under normal pressure, keep it light enough that you'll actually hold it, and don't sweat the speed and attachment counts. A simple gun you use every day beats a loaded one you never touch.
