Sears website says $60 with $10 rebate, but in the store they are
marked $50 flat, no rebate required.

I've been pointing mine at everything. Our pets, the ceiling, stuff in
the fridge and freezer, the inside of my computer, myself, etc.

One important thing to know: it's calibrated for an emmissivity of
0.97. That means anything light colored is going to read as a lower
temperature than it really is. Like a silver bottomed iron. Easy fix-
stick a piece of dark heat resistant tape to the iron. Measure on the
tape, then measure on the untaped silvery bottom and you have a fudge
factor. Now you don't need to put the tape on the iron again.
