Bests & Worsts Reviews from Amazon

I recently got this thermometer form my mother in law who is 91 years old. She needed something easy to use. I have a Braun forehead thermometer (which is touch - not infrared), so I compared the temperatures and this thermometer was off by 0.4 degrees, which made me suspicious. I decided to read the manual and I found information on how to calibrate the device, which is very easy to do: you are suppose to use another thermometer to measure your temperature, and then use this one. After finding out the difference of the temperatures you can add or subtract degrees in the programing menu and that will do the trick. Also, it can be use for both C and F - which is great, since my mother in law does her readings in Centigrades. Another heads up - as soon that you put the batteries and turn it on for the first time, the letter M will blink on the screen. You have to then follow the prompts (look at manual) to set up the scale (F or C) that you want to use. I am glad I found this thermometer because I tried few different ones (one from Amazon that was so bad that when I decided to write a review about it the product was no longer listed), one from Walmart ( I couldn't even give 1 star) and one from Walgreens (which was measuring the temperature all over the place). We are happy with this one. I just wish it was a little cheaper...
