I don't know why these would fail in the same way, should I go with a
normal honey well thermostat?
(non digital).

Were both failures or the same model? Maybe a bad design, or both made with
components from the same batch. Certainly, I would not BUY another one of
those, unless you get it under warranty.

If you must have an electronic one - maybe Consumer Reports has some
ratings. Else get a simply mechanical one - they last forever.
