Setting the high and low alarm levels is a painful and not very easy task. Even then, trying to change it is a PAIN. Right now as I posted it the reading is only 2 degrees above the actual water temperature. I tested this with a knot thermometer and a regular thermometer. Still useful, but you just have to keep in mind that it's turned off. I haven't moved it which means the tacky adhesive isn't dangling. But maybe it will give me more accuracy in the future.
