Comfier 2405 Portable Back Massager for Chair with Heat and Adjustable Kneading

I keep this on my office chair and it's transformed my workday. The kneading is adjustable, and the heat helps with my chronic back tightness. It's quiet enough not to disturb colleagues. Highly recommend.

The massage is strong and the heat is nice. However, the placement is a bit high for my liking — I wish it sat lower on my back. Also, the strap could be longer for bigger chairs. Other than that, it works well.

Bought this for my dad and he loves it. Easy to use, comfortable, and the heat really helps his old injuries. It's become his favorite chair accessory.

It works great initially, but after about 15 minutes, it automatically shuts off to prevent overheating. That's annoying because I want longer sessions. I wish there was a way to extend the timer.

I use it on my couch, car seat, and office chair. The straps make it versatile. The massage is a bit intense at first, but I adjusted the settings. Good product for the price.

My doctor recommended a massager for my sciatica, and this one specifically targets the lower back. The heat and kneading combination works wonders. I use it every evening and the pain is much more manageable. Thank you, Comfier!

I was happy at first, but it started making a grinding noise and then stopped heating. The massage function still works, but the heat is gone. I'm disappointed considering the price.

I'm a gamer and I sit for hours. This massager fits perfectly in my gaming chair and the heat keeps me relaxed. The adjustable kneading lets me set it just right. Excellent purchase.
