I have a helix and to be honest I'm not crazy about it. I get about a 3 degree swing on my incubator. I think I'm going to try a vivarium electronics from reptile basics. Have you looked at those?
I asked on here earlier about the vivarium electronics from reptile basics and no one had anything to say about it. I don't know anyone who uses them but RB seems positive about them- but then they would...so I don't know.
Has any one out there tried it?
