Query: Inaccurate

I bought this in anticipation of a liver transplant. I knew I would have to take my temp several times a day in the weeks after the surgery. Unfortunately, this thermometer was horribly inaccurate. I could take my temperature one time and I would show that I was running a fever. I could reset it and take the temperature again and it would show that it was below normal. The fluctuation could be as much as 2 to 3 degrees at time. I even checked it against the thermometers used in the hospital and it was always off by at least 1 degree.Very inaccurate and potentially dangerous. Don't waste your money on this one - go with BD or another tried and true medical brand. Timex needs to stick to watches.
