The Hydragun comes in a case for carrying it around to the gym or office.

Massage guns have become very popular lately with athletes engaging in sports and fitness activities; as well as people working from home, using home furniture not suited for extended hours of work – resulting in poor postures, back & shoulder aches and carpal tunnel syndrome in the hands.

So a good massage gun has become a must-have for working adults.

The Hydragun is a Singapore-designed, China-manufactured massage gun targeting sports enthusiasts from all walks of life.

Starting from the packaging and the design and build, you can tell the company is serious about making a tool that provides effective healing and recovery for sports injuries or work sores and aches – unlike many no-brand OEM products on the bandwagon that was hastily thrown into a box with minimal documentation and sold for a song.

The S$399 Hydragun alongside a S$50 OEM massage gun from a friend who bought it online. The latter was heavy and unbalanced, had no return policy or warranty and stopped working after two months even though it was hardly used. The Hydragun comes with a 30-day “No Questions Asked” Return Policy and an 18 month-warranty.

In the box, the Hydragun comprises the main vibrating therapy massager (the big gun), six head attachments (four regular, two with stainless steel heads), one charger, one manual, and a robust zippered case to easily carry it all to the gym.

Unboxing the Hydragun percussive therapy massage gun.

The massage gun is black and made of aluminum alloy and nanoscale silicone wrapped around the handle.

I like the red metal band at the rear of the gun – it serves as an accent against the jet black body.

The aluminum alloy makes the Hydragun lighter than the majority of such massage guns in the market – I’ve tried one of those and the massage gun in itself gives you sores and aches from just holding it!

The nano silica gel wrapping the handle gives it a non-slip premium grip and does not leave a sticky residue from post-workout sweat – unlike plastic handles.

Holding and operating the Hydragun, what impresses me is how balanced the massager is.

Other guns I’ve tried are not only heavy, but the centre of gravity (CG) is top-heavy, so when you grip it in your hand, it feels like the gun is pulling away from your grip and falling out so you have constantly exert strength just to grip it tightly to avoid letting it slip out of the palm.

I believe the 1-kg Hydragun’s CG is roughly where the hand grips the gun, so it feels balanced and doesn’t feel like it’s pulling away from the palm.

When it’s being used, I can focus my grip and attention on positioning the head of the massager rather than being distracted merely with holding the gun properly.

In operating the Hydragun, everything can be controlled with a single button at the centre of the surface behind the gun.

Long press to switch on or off.

Once on, single press to start the vibrating at Gear 1 (1,300RPM) – there are six levels with Gear 6 (3,200RPM) being the fastest.

A horizontal row of six LED lights shows which gear the gun is operating at.

Three LED lights below the power button shows the battery power.

How hard the massager is whacking your muscle is controlled by how hard you press the vibrating head onto your skin, and the amount of pressure applied is displayed by the torque meter using three LED lights above the power button.

Which gear to use and how hard to press is really subjective, so just begin with Gear 1 and increase it until you feel it is just right.

The single-button control and indicator lights at the rear of the Hydragun.

You have to avoid the bones, and the manual provides a list of medical conditions when you should get your doctor’s advice on whether you should be using massage guns in the first place – such as pregnancy, pacemakers, herniated discs etc.

My Take:

The Hydragun worked wonders for the muscle ache from my gym workouts, as well as the sore neck, shoulders and neck from working on the computer. I love how silent it is, the balanced CG and non-sweaty grip. Highly recommended for both serious sports professionals and enthusiasts as well as for normal sores and aches from work or chores.

The Hydragun takes about 3.5 hours for a full charge and the 2600mAh battery is supposed to last for 7 hours.

However, since typical massage sessions last for only 10 minutes, there is no worry of the battery running out on you since you can always plug the Hydragun in to charge when not in use.

The charger plugs in at the base of the handle – you’re not supposed to use the charger when it is plugged in!

There is a safety feature that cuts off the power after 10 minutes of continuous use, in which case simply let the massage gun rest for 2-3 minutes before continuing.

The Hydragun comes with six interchangeable massage head attachments for use under different circumstances.

One thing I love about the Hydragun is how quiet it is.

It is so silent that I can use the gun while watching TV or having a casual conversation with someone (who doesn’t mind me using the gun while chatting).

    Does the battery drain very fast? Do you keep it plugged in when not in use like the vacuum cleaner?

      No the battery lasts forever. My each massage session lasts only 10-15 min but the fully charged battery is supposed to last for 7 hours so don’t worry about the battery running out on you mid-use. Just plug in for a good charge when the battery indicator shows battery low. You’re not supposed to keep the Hydragun plugged in all the time. Only plug it in when you want to charge it, and unplug it once done. Stow in box when not in use.
