The best cost performance and coolness

It's sturdy and the size is just right.
But is there a part inside that is damaged?
It's rattling.
First of all, it works well.
The price is very affordable.

The quality is good, but due to the gap between the upper and lower massage balls, direct neck massage is actually difficult. Massage of the shoulder and top of the collarbone is possible.

Um...um...um...........
If you really want to buy it, then instead of this one, go for the gray and light purple color...
The product quality is good, but when actually using it, the height of the upper and lower cushions doesn't match, making it uncomfortable.

Good
