I use inkbirds as temp controllers. I have my tanks (8x2.5x2.5) (4x2x2) outside which isn't the best option. The back and sides of the tanks are insulated. i use schego titaniums at 600w because they wont shatter. the inkbirds have never missed a beat. i think they are a great option.
i currently live in Cobar, so its hot in summer and cold (-2 overnight) in winter.
I hope this helps.
