I have one that came from walmart and paid $19 for it and it is stronger than this one. No matter how hard you push on the one from walmart it won't stop. The PCA004gunwill stop with only a small amount of pressure. Would not buy it again.
I’ve had mine since 2018 and it is still working in perfect condition. Worth every penny!
They should make it accept enough pressure to reach the muscles.
I love the gun but I don't love that it no longer comes with a case which means I have find and buy one or keep it in a box.
