HOVABATOR therms. are JUNK!!!
OK, I just posted about my Hovabator fluctuating. It turns out, shortly BEFORE I went to raise the temperature because the thermometer read 76o, The temp. felt pretty warm to my hand, so I hit it with my Tempgun ( I used this and the Hovabator included piece of JUNK!!! to initially set it up) and low and behold I'm at 89-90o F. I ALMOST cooked ALL of my first years eggs...
So I am slowly dialing DOWN the temps, back to 82o.

Anyway I'm looking at the Hovabator thermometer and I realize that there are two tiny pieces of wire holding it on to the flimsy plastic degree marked backing and that with the slightest pressure ( Ohhh...something like pushing it into the incubating medium to get an "accurate" measurement) will SLIDE the Darn thing producing a COMPLETELY innacurate temperature measurement...There isn't even a mark on the backing to show where it should be placed, so it could be innacurate right off the bat. I almost lost more than a K of eggs for the price of a drop of glue...Needless to say it's in the trash ( there's no mercury in it)

PLEASE ADVISE ANYONE YOU KNOW WITH ONE OF THE HOVABATOR THERMOMETERS TO THROW THEM AWAY!!!

I'm posting this on a few other forums, please feel free to copy this and put it anywhere else they may be used. I'm going to contact the company about this also.
