I have many Opatra device's, they all as far as I'm concerned, do the job.
When I saw this new device, I had to have it, as a retired therapist I know the power of EMS, and when Opatra add something to their products, I've learnt it works!
This is a powerful handheld machine that has already sculpted my face! It may seem a strange sensation to those who haven't had EMS before but just persevere and see the results, five stars!
