The convenience of the rocker system is that you can walk away from it, as long as it is rocking, instead of constantly watching the dial gauge and having to adjust the heat.
That's the route I took with my presto.It's much easier to just forget about that dial gauge.
It's just my opinion here.I'm one of those people that will have it tested,corrected if need be.And that would be it.We all know they need to tested again after what 2 years?..I know I'd forget to do that.So buying the extra pieces and can when I want,year after year.It seems to be for me anyways the safer way to go.
