During the time it was working, it was exactly what I needed. Unfortunately, its lifespan was extremely short.

In a few minutes of warming up, it is ready to use. Its plug also functions as a thermostat, which turns off as soon as it reaches the desired temperature with a characteristic click and the red light goes off, so you don't need to supervise it. In the first uses, it has an unpleasant smell that fortunately does not linger on fabric or skin, for me after 6-7 uses, it no longer smells.

Excellent product! It smells very little when you plug it in. Its power corresponds to the watts and its duration is great!
The size of it is extremely convenient!
I highly recommend it without hesitation!

In just a few minutes, around 7 to 8 minutes, you have something that can relieve your pain, whether it's muscular or stomach pain, and generally something that can keep you warm during the cold winter days and nights for 2 whole hours. It is extremely soothing and portable, without the need to constantly have it plugged in. It is also very easy to use. I recommend it, it is worth its money and more.

It was purchased 2 weeks ago. Initially, it was working perfectly. Now it barely heats up. Disappointing lifespan.

Tremendous discovery. I have it with me all the time, I no longer need to beg for water from a kettle, neither in houses nor in taverns. I use it for many reasons, pain, warmth. It lasts for many hours and is very hot at the beginning, so much so that some people can't handle it. I put it in my bed and it stays warm until morning. It's a bit small but very convenient if you want something small, for example, on the neck
