I know I am alone here but here goes, and then let the stone throwing begin. I have never had any luck with PTC in an NA application. In fact I would go so far as to say had nothing but problems. Customer service was great but way to many issues with simple things soured me on them.

We have had excellent luck with ATI and A1 over the years. Probably purchased 30+ converters from the two of them. I have tried many and always end up going back to these two, depending on the application.
