Just received a flyer for one of these and was womdering if anyone had any experience with them. The are one sale for $50 off the normal price of $319.

If you have one do you use it much, and do you charge for a diagnostic service?

How does it "test....all splices and connections"?

I have an Ideal tester that performs almost all these functions. I use it daily...I always test my work. I also go through a whole house testing all accessible outlets & GFCIs. I charge for all services except warranty work.
