First of all, it is entirely made of plastic. I had bought 2 with the intention of giving one to my mother. In the end, she didn't want it and I kept it for myself. The first one fell apart in my hands as I was unsuccessfully trying to insert the battery. The second one, surprisingly, is still alive and I keep it like a fragile doll, afraid that something might break. It is one of those products that make you wonder which defective piece from the batch you will get.

It's not made of pink marble. It's plastic. That's its main disadvantage. Also, the cylinder doesn't rotate. It didn't have a battery inside as stated on the package. Also, the instructions on the box are upside down for the heads. The vibration intensity is good and it seems to work fine as long as I used it. The feeling is like rubbing plasticine on yourself, since the "stone" is plastic and of course the temperature doesn't change in the fridge to cool it down

I used it a few times - from the beginning there was a problem with the battery placement - then it fell apart in my hands. It is not stable and I do not understand how such a fragile product can be effective.

Fake with fake plastic, the second attachment and the button broke within 1 minute of changing the roller with the other attachment and pressing the button, to try it out, I see some got it at the price of 3 euros, unfortunately I got it for 6 euros for 2 pieces...
