I purchased the belt for the back and the ones for knees for my husband.(Who suffers from chronic pain.) We were skeptical but the belt for the back actually fades his pain a little. As we say a little is better than none.

The best massager I have ever had. I have restless leg syndrome. This has several heat settings and helps with pain relief. Amazing functionality and heat helps relax the muscles. Very portable to carry along while traveling. I highly recommend this product.

Versatile, easily adjustable, heat and vibration.
This offers heat and vibration for shoulders, knees, and elbows.This set is especially nice because it is a set and you can do two body parts at the same time.Had multiple setting for both heat and vibration, three for both adjustments.These are very adjustable and have extra length straps to make then usable for shoulder as well as anyone who may need even longer adjustments.Usb charging cords included, these did come already charged which is nice to be able to use right away.I find the heat and vibration very therapeutic for both my sore knee and elbow that occasionally get flare up after too much use.Great therapy device to have in hand for joint pain in elbows, knees and shoulders.

Well kept massaging heat kit.
Nice compact set, includes charging cables (USB C) for each of the knee sets, plus velcro extensions to use the kits on your shoulders, elbows or other.The temp settings are only in Celsius, can't change it to Fahrenheit. When you initially turn them on, there's no temp setting per se, it only displays what the current temp it is at. You have three levels (Low-Med-Hi) to set it at. As the temp rises, the display shows what it's at.

Nice for heating, so so for vibration
I have various knee issues and am always looking for ways to ease pain, recovery, etc. in the knees. I got these mainly for the heating function to help sooth my knees in recovery and with them being wireless that is a huge pro so I can still get up and get something without taking them off/on.

I wasn't sure about this since I've purchased other heated massagers before but this really proved me wrong. I can definitely feel the heat and massage.

Giftable
Like that its a 2 pcs for the price. Does feel the warmth and vibration is comfortable. Like that you are not attach to cable as this is rechargeable.

This massager works great! It has 3 different heat settings ranging from approximately 130° - 170°F. It also has 3 vibration settings. It works well on knees, elbows, shoulders and ankles/feet. I was also able to make it fit my hand and wrist. It is rechargeable, do no annoying wires getting in the way. The battery lasts a long time. I used it on both knees and elbows for about 15 each and still had about 50% battery left. It seems well made too.

Helps ease knee pain.
Very easy to use.Fits well and is secure.I ordered this for my mother who has knee issues. He uses a knee brace on a daily base and when she rests she uses these. The warmth and the massage/vibration helps ease her knee pain.

It feels amazing! There's no other word to describe it!! The heat it's nice and the vibration makes an amazing massager. Definitely worth every penny!!
