I haven't used it many times yet but am pleased with all the functions and I can watch the food temperature without opening the oven door. The numbers are a good size and the unit itself is magnetic. As I have a double oven, I can attach it to the oven door at eye level, which is a bonus. This was bought at an extremely attractive sale price, as I have seen it elsewhere for double the price I paid for it.
This item was just the right size for what I wanted. I bought a door mounted spice rack to go on my pantry door but this was a bit bigger to fit those slightly larger items and it fitted nicely underneath the spice rack.. Very pleased with it.
