### ⭐⭐⭐⭐⭐ Works well
*by S***N on December 17, 2025*

I have this set up for my attic. The receiver isn't particularly close, but I still get good measurements. The fact that it lights up when you touch it is a bonus. There is a mounting hole on the back of the receiver, but I purchased some magnets, and I will use those to attach this to my refridgerator. The instructions are clear. This unit does NOT interfere with my other wireless thermometers made by a different brand.
