Got this comb thermo/hygro digital Flukers because of all the rave reviews. Well, mine is schizo-thermo! It will read a steady temp, say 99.5 then suddenly without any in-between numbers, jump to 101.5 or something. That cannot be. Then it will jump back down to where it should be. The AcuRite is not so "jumpy" and I wonder if I should return this darn thing! It just can't be trusted at all. I've cleared the min/max several times, removed and replaced the battery. It's still wildly flucutating. Anyone else have this problem with theirs?
