It is in the title, for the price, the plastic is surprisingly nice "touch" better than other more "pro"! Mainly used in my area to check the temperature of billigs (270 ° ~ 310 °), refrigerators (4 ° -8 °) and freezer (-22 ° ~ -26 °) at precision, not much difference (not more than 1 or 2 degrees along the beach) with my "Pro" Version costs 10 times more expensive ... To see maybe in the long term, but in the state (and perhaps luckily) I recommend and recommends another to offer! It is certainly very useful and almost indispensable pancake!
