I have ordered, and yet to receive an "AkuSpike" mat to see if it benefits the neuropathy in my feet. Apparently, this mat https://www.akuspike.com/ is a step above other acupressure devices, in that "Aku products are meticulously designed with high-grade metal spikes that naturally stimulate energy flow throughout the body. When conductive metals, such as silver and copper, come in contact with the skin you'll experience a natural warming effect that is both healing and therapeutic."
I should receive this shortly, and will take it on a Caribbean trip in another week. I'll certainly report back to this forum, especially if I find it DOES actually work!
