Deciding to get into the massage phase and not knowing if this type of massage would suit me, I bought the cheapest one so that if it was useless, I would have only lost a few bucks. In the end, the massage type is satisfactory, and surprisingly, the machine is very good for its price. Its external quality is acceptable, after 2 months it hasn't had any issues except for the hole where the heads go in, which has opened (without causing any problems and maybe it's better that it happened). In terms of functionality, it's great, it's quite powerful and lasts a good amount of time (about 20 minutes, then the performance drops and it needs to be charged). Unfortunately, it has a short charging cable, but it's a minor problem that can be solved anyway... When you massage at an angle and not vertically, it makes a noise as if it's struggling, but it might be because of the head that is in the hole and that's why it opened. We'll see. Clearly, it can't compete with devices that cost 100 euros, but for its price, it's excellent
