I bought this for my 93yr old mother - her hands get stiff and start hurting as the day goes.
I was surprised that it came charged right out of the box and stayed with a full charge for about 3 total hours of use.
It is very easy to use and the manual is easy to read without a lot of technical jargon.
I was a little concerned about the possible issue of too much intensity for her but was pleasantly surprised.
My mother loves it ! It gives her the right amount of compression at the lowest level and the at 15min intervals it gives her the relief she needs.
I tried it myself at the highest intensity and the amount of compression wasn't what I need but for someone who needs a low to moderate amount of compression, it seems to be just right.

Bought this for painful hand. Does not work miracles but does soothe the pain and tingling somewhat. No issue with the product itself but very disappointed that the one I received was used and repackaged. Everything was haphazard in the box, empty plastic bags, label reapplied (sloppily.) Sheet of stickers was missing half of them, not that I needed them but just the idea. Battery was completely discharged with charging cord thrown in box. Was about to return but decided to give it a chance to see if any defects. Battery seems long lasting after recharge. Massage and heat working but don't expect much from heat as it more or less just keeps slightly warm rather than any type heat therapy.

I was very hesitant to buy this because it received a 'C' rating on Fakespot. I looked at all the other hand massagers on Amazon but I wanted one that compressed each finger individually. All the other massagers on Amazon look like they are rebranded copies of the same model that don't wrap each finger but press up/down instead. I'm not positive on that because I've never used any of those. But I can speak on this Comfier massager. (For reference: my hand width is 3.5", length is 6.75" from beginning of wrist to tip of the middle finger, and width of fingers is 0.6")

1. Massage: As their photo suggests, this hand massager does wrap around each finger and the other four points and compresses with air; very much like a strong blood pressure cuff. It includes 3 settings of pressure, which defaults at a yellow light indicator or medium. A green light indicates a lighter compression and a red light indicates harder compression.

The air pumps in a predetermined routine. Something like this: The palms compress along with the three middle fingers, then decompresses, and the thumb and pinkie compress, along with the palms, and decompresses. The routine makes it feel like it's rolling/kneading during the massage. BUT the best part of the routine is this! All of the bags compress and hold for a few seconds then release. The feeling is so pleasant when it releases.

EDIT: I discovered that pressing the center button changes the routine pattern! So there are 3 massage options to choose from.

I personally use the red/highest pressure setting, but medium feels good too. The lightest setting is too light for my liking however I can still feel the compression. For those with larger hands than my tiny man hands, the levels of compression will probably feel all that much better.

2. Heating: The heating element only heats the palm, however it does feel like the heat transfer up to the middle finger knuckles to me. This also has 3 settings for heat temp with the same color indicators as above. At the highest setting I measured this to be 98 degrees using an infrared thermometer. It feels hotter than that though so the thermometer could be wrong.

3. Noise: The pump is measured at 57 decibels at it's loudest. The sound that it makes is more of a vibration sound than a pump; if that makes any sense. 57 decibels is between a refrigerator and a conversation. If you plan on taking this to a loud office, it may go undetected, but people next to your cubicle may question what you are doing over there.

4. Battery: When I received my massager I was excited to try it out. Unfortunately it doesn't come precharged. This massager does that at least 3 hours to charge before you can use it. Once it charged I used it unplugged on the highest heat and highest pressure settings. The massager is set for a 15 minute massage. On a full charge I was able to get one full 15 minute massage and the second massage the battery ran out of juice half way through. I'm able to get two full massages without the heating element on. It makes sense as I'm sure the heating element uses a lot of the battery.

I read a Q&A if this could be used will plugged in and Comfier responded with, "NOTE: This hand massager can't be turned on while charging." on 11/18/21. I'm letting you know that YOU CAN USE THIS WHILE IT'S PLUGGED IN AND GET FULL USE. It does have to be charged first before you can turn it on. I'm unsure as to why I can use it plugged in. It could be a number of things: Comfier responded to that question in November 2021, so it's possible they upgraded the device? Or maybe it's a safety hazard to use it plugged in? I don't know... but I use mine plugged in multiple times a day and yet to have any issues or concerns.

5. Quality: The build quality of this massager is excellent. The device looks sleek where it can be placed anywhere without looking like an eyesore. The massager feels very durable and well put together. The outer plastic shell is thick and the inner fabric is soft and silky. The fabric is also moisture wicking. If the exterior of this device is this good, I'd hope it be the same with the inner components for a long use cycle.

TLDR; I highly recommend this hand massager for those looking for some pain relief in their finger joints. I can't speak on arthritis, carpal tunnel, etc since I don't suffer from those diagnoses. The Comfier massages around all fingers and the palms very well with air compression like a strong blood pressure cuff. The heating is on the palms and may reach up to the middle finger joint for some with smaller hands. The device isn't too loud, build quality is excellent, and it looks very sleek. The battery life is good without the heating element on. Lastly, it does come with those cute stickers you see in some pics if you were confused. My daughter stole them from me.

I bought this for the pain at the base of my thumb. The tunnel for the thumb should be more to the side. The other four fingers fit into the tunnels. The unit is new today. My palm feels good on the lowest massage setting. I don't know if it will help my thumb pain. I will give it a try.

I'm a dog groomer of 15 years and have arthritis in my hands and I use this every night after work. It's so soothing and such a sturdy machine. 100/10.
