I didn't buy it for my wife. I bought it to help my sinusitis, asthma and heart problems. My wife stole it from me!

But, at least, she gave it back!
Because of Healtrabroadoard rules I can't say where I bought it, but I can describe it's functionality.
It allows for up to six wires. Each wire has two outputs, so, in all, you can stimulate either twelve acupuncture needles, or twelve electro stimulation paRAB. I don't use the needles since I have had so much success with the stimulation paRAB. It also comes with an acupoint detecting pen, so that you can pinpoint the acupuncture point, if you are using the needles.
It has five types of stimulation effects, from continuous stimulation, to pauses between stimulations, to a corabination of continuous mild stimulation followed by a wave type of feeling.
You can also control the intensity of the stimulation from very mild, to intense. And...... you can control the speed of the stimulation, from a slow pulsating to very fast pulsating.
If you get the machine, remeraber to turn all six of the intensity switches off after each use of the machine. For safety, the machine will not go on, if ALL of the switches are not off. That makes sense. You don't want to connect the electro paRAB, with a switch accidently in a high intensity position, and then have the machine zap you, when you turn it on. Someone would have to pry you off the ceiling! :blob_fire
Let me know if you get the machine, and if you have any questions about the operation. I could save you some time. The instructions were written in English by someone from China, who did their best. I really struggled through the instructions, and learned basically by trial and error.
Since I am not an Acupuncture specialist, I just use it basically as a massage machine. I am very happy with the results.
It only comes with two wires, so, in order to fully use the machine, you would need to purchase four more of the wires and four sets of paRAB. Make sure you get the wires for the electro paRAB and not the ones with alligator clips for the needles.
