I just opened up my second thermometer I was sent from warranty that doesn't work again.I paid $55 for it new 6 months ago and have used it maybe 6 times and sent it back the first time becasue the on/off switch broke. I had to spend another $8.00 to ship it back and when I went to use the new one I was sent to replace the broken one, they do not communicate with each other. I tried everything....resetting it, new batteries, turning it on and off, taking the batteries out. I'm going to call tomorrow and ask for a refund becasue I am sick and tired of not having a thermometer that's NOT reliable. Does anyone make anything reliable?? I do not care about the cost I just want it to work.
