i dont like that zilla or the zoomed thermostat.why?
well all the others are proven and fairly durable.
they can be adjusted without need to check the temp at the probe.
you can also adjust how many degrees before it turns on.
some can be later expanded with night drop.
some just have everything and can also be used on an incubator at a later time(proportional ones).
some you can replace the probe if something should go wrong with it(rodent bite, broke wire, random stupidity pulled probe out)
