I have had it in my possession for about four years, I bought it to have the ability to relieve spinal column pain when it arises without having to go to physical therapists. It is definitely worth its money, personally I have not regretted this investment. What I would recommend to every new buyer is to stock up on extra adhesive pads.

I have purchased this machine twice for the physiotherapy laboratory of the school where I work as an educator. It is excellent. Despite heavy use and abuse from many people, students, etc., it didn't show any signs of damage. Even when the cables were damaged from the channels, with a little effort they could still be connected and it worked perfectly.

I gave it 4 stars for whether it's worth its money for the simple reason that here in Greece it is sold for 30-35% more than it is sold abroad (like many other things). But even at such a price, it is a device that is worth it.
