Do you calibrate it with something accurate? Some suggest checking ice water, and then boiling water. Thats not a bad idea, but doesn't mean it's accurate at all points. I'd suggest having two, and checking those against each other as well.
I have a Thermapen, and I have a spirit filled, lab grade glass thermometer to check each with. I use the Thermapen mostly, but will randomly do a check to make sure they both read the same, and they always have luckily. The lab grade one was roughly $60, but I had an extra from work, so I lucked out there. You can find them for pretty cheap online if you shop around.
I have 3 other thermometers, and none of them read the same as these two. Some are closer than others, but calibrating them makes a difference. Makes aiming for a temp, and reproducing a recipe hard if you aren't mashing where you "think" you are.
Be warned, Thermapens aren't cheap, but they aren't ultra expensive. I used mine for more than just brewing too!
