I have an electro sound. I was introduced to electro cath play by someone else who had an expensive box unit that had all kinds of different programable settings, cycles, etc. Without a doubt, you could program a climax. I bought a cheap basic TENS box....with the same electro sound, I can still get the jolts, but not the same rhythemic cycles. Suggest if anyone wants to experience everything that electro sounds can do, you need to purchase the $300-400 power boxes.
