Hello all!

I am looking to purchase a professional microcurrent machine for my spa. Im finding it difficult to research which ones are truly the best, and what properties of a microcurrent machine would even make it better than others. I see some with just prongs, some with a rolling device over the face, some that are just two electrodes. The one from england The Caci machine looks amazing, but it isn't sold in the us. 

Anyway, have any of you purchased a professional strength machine you are really happy with? Do you get what you pay for with this type of machine?

I appreciate any and all responses as I am lost among a sea of equipment!

Thanks!!
