I use the top one, the Inkbird, too.@Ray--Opo I use this one: https://www.amazon.com/dp/B01486LZ50/?tag=exoticpetnetw-20
Although a lot of people recommend this one: https://www.lllreptile.com/products/13883-zilla-1000-watt-temperature-controller
I have one and it worked well and is easier to use, but I like the nice temp display on the Inkbird ones. Hope that helps!
