The USB-A connector is there probably because of its resistance to washing
great for warming your back
depending on the degree, it can heat for 6-8h
to support the back useless

see above
It's really warm
Foldable
Looks good quality
Unfortunately, as someone mentioned, it's made for thin people. It's not so much the width of the belt as the length. I have it zipped up to the last velcro and all I have to do is breathe a little when I'm sitting and it unzips, it doesn't hold at all. And I'm not fat, I'm just over a pound. So I'll have to figure out the buckle somehow because otherwise I'm happy with the belt.

Possibility to throw in the washing machine
It's so narrow! Siguro can't be serious about this, for grown men. The lap belt should be made so that the height covers all problematic organs
The power bank is not mentioned in the product description, nor in the advisory, just nowhere - that is, the connector, which is at the belt is not USB-C as ours in the 21st century would expect but some completely different connector, so I have to power it so what?
If you want a warm belt choose another

Hello, thank you for your review and I am sorry that the belt did not meet your expectations. The Siguro Comfy Belt S350B is designed as a compact lumbar belt with targeted warming. Its width is chosen to effectively cover the lumbar spine or, in women, the lower abdominal area for relief from menstrual pain, not the entire abdominal area. The dimensions are given in the product details so that the customer can check in advance whether they will suit him. As for the power supply, the strip is terminated with a specific flat connector that is fully compatible with the classic USB-A port (a common input in most power banks or adapters). Information about the need for an external source is included in the description. If necessary, please do not hesitate to contact us. Thank you and have a nice day, Ondřej - Alza expert

The heat is very intense and relaxes stiff hips beautifully. The highest gear is too much for me, I don't even put it on max. The controls are very simple, charging via the powerbank goes well and it is great that thanks to this it can be unplugged from the cable and then thrown into the washing machine. I recommend it to everyone who suffers from hip, disc or menstrual pain.

The Siguro Comfy Belt S350B heated belt is very comfortable to wear that you can't even feel it, the big advantage is that it has three temperature levels, easy to operate. It has a powerbank pocket so it can be carried during everyday activities, the downside is the shorter cable.
3 temperature levels
easy temperature switching

It is easy to fasten and is a soft touch, soft material. The belt heats up immediately after switching on and gradually increases in temperature. I would appreciate a higher temperature. I was nauseous after a bad meal, I had cramps and pain. I had an estimated 15m waist. on my lower abdomen and it was a nice pain reliever and I relaxed so much that I fell asleep.
Soft material
3 heat intensity levels
Machine washable
Different sizes (long velcro)
Powerbank pouch
It warms and relieves pain beautifully (I had cramps after a bad meal and it relaxed me nicely)
Helps to relax
It doesn't fasten well to the lower abdomen (it doesn't fit perfectly, as I would have imagined)
It only works on the powerbank, which is perhaps a bit unfortunate as it sometimes gets in the way
I would have appreciated a warmer temperature

This heated belt is an excellent product that offers instant relief from menstrual difficulties and back pain. The belt is easy to adjust, and its temperature is quickly adjusted as needed. Choosing the heat intensity is a breeze, and the quality material makes it really comfortable to wear. After use, the cable is easily detached and the belt can be conveniently washed. I recommend it for anyone looking for effective relief and comfort.
immediate relief
