These were some of the last Pso-Rite products I needed to finish my collection, and I'm realizing that I honestly didn't give these things the credit they deserved. I'm always looking for deep tissue release, so I overlooked anything smaller than the Pso-Mini, thinking that anything this small wouldn't have much to offer me. Wroooong - BECAUSE these things are so small, they offer some serious pointed pressure. I'm finding these super helpful in accessing the small muscles of the hand that I wasn't hitting as deeply and pointedly using larger tools. It's also been incredible for my TMJ - much easier and faster to release the muscles of the jaw and face using this than with the broader angle of larger tools, which can be awkward to position on the face.
Don't forget you can also use the thinner part with the keychain hole - that little nub will dig like hell in between the tendons of the hands and feet (and face, but I did that once and went a little ham and left little dents on my face for a few hours, so you've been warned if you're going out in public lol). I also like that it comes with so many, so you can have them on a few sets of keys, gift them to people, and keep some off key chains altogether so it's easier to use the nub too.
Another amazing product from an amazing company. They have mind-blowing service too, so fear not - any unlikely issues will be dealt with in ways that will impress you and make you want to tell all your friends. Can't want to see what Mac invents next!
