Product review (4 stars): Awesome; but you do have to open it up and solder to make it read Fahrenheit
I wasn't expecting this thing to be so small.
it's still works great. I'm on the states side and everything I use is in Fahrenheit.

After reading some of the comments I saw that you can switch this to be Fahrenheit, of course when I first bought it one of the images showed Fahrenheit so I knew that it could do so; I just thought it was a simple switch.

And for the most part it is a simple switch; they just didn't include the switch.
After opening it up i found the 3 pins and the one marked F the ground pin is the center one.
So just by dropping a bit a solder to bridge the two pins it was reading in Fahrenheit.

Easy fix.
