Product review (1 stars): Defective out of the box
We bought two to use in our egg incubators. One was defective out of the box - where the wires attach sensor lead to the back of the gauge are loose, and you have to shake it to make a connection, then carefully set it in place without jostling them again. Plus, this is more the style that should be clipped into a permanent board of some kind, not for free standing use. Did not  see or read that in the description, but the inexpensive housing for the gauge has what looks like built in clips to press it into a board of some type.
