I looked for several other models for my thermo and hygro. I just wanted something not so huge, not so complicated but very intuitive. This item worth my money more than enough and it has a magnet at the back, so I can just put it on my freezer. I liked to size very much. Adequately small but the letters are big enough for me to check from across the room (without my eyeglasses) I am very satisfied with this!
