They work by using electromagnetic wave therapy. Basically, it sends out small pulses to help with inflammation or arthritis. Some pets respond differently to it, but I've had three use it and all three seemed to get relief from the treatment ☺️

It did take me a while to save up, but personally I think it's worth it because it lasts forever. I've been using it for several pets who have struggled with arthritis and it's really helped them. But again, it's not for everyone. Sometimes oral meds are just as effective.

It was around a thousand dollars, but there are smaller versions that are cheaper. Some come in loops that you hold over the pet, but my vet recommended this one. I'd say it's definitely paid for itself, it has really helped a good majority of my seniors.
