Sorry to hear the BM21 has shingles. I had a case once and it felt like these were piercing my scalp.
I hate to go on the deck with those hanging overhead. Even though they are small they look lethal.
And Veebs...all thermometers are not created equal. Note ours stops at 80 (just the dark part of the dial) but goes down to Minus 40. Thats what I'm talkin about!
