Hey again!
I am not sure where to get them etc, but I bet they will work just fine. I don't think I've ever seen them, but as long as they have somewhere to connect, you could use them. The ZP Zapper uses aligator clips just like a lot of the other Zappers. The Gel Pads are probably mainly recommended because your boys would likely not enjoy sitting still for 7 minutes (a long time!) holding onto the pipes. They maybe have better contact as well.
If you get the ZP, I recommend you request the copper rings (free with it). They are adjustable, and easy to keep on because you can be fairly active while Zapping. They seem to have really good contact!
Oh, I have to share this... I decided to Zap again last night before going to slepp, so I did 2 regular 7 mintes, then I decided to put them against my shoulder blades. Well, I got a little jolt! It was kind of like the tissue relaxing therapy. Any way, it didn't hurt, but it kept sending little jolts. It relaxed me, so I took it off when it finished and went to sleep. Well, I woke up with it under my shoulder blades again! I do the craziest things in my sleep...
