Used the deep fryer on a trip to Minneapolis this past weekend. Kept it at a pretty low temperature and on my first try, it must've reached the temp and powered off. I was a little worried because there was a sprinkler right in the bathroom above the outlet, but when I took a shower, I couldn't get the hot water adjusted too well and really steamed up the place, so I figured I was fairly safe.
But it worked really slick and I didn't set off any alarms or sprinklers at the Doubletree.
