I purchased 2 Judges , both seem to work well BUT one will clip to the mount and still fix to the mount. The other one never has stayed clip to the mount , I had to improvise to get it to stay mounted. Both units generate lots of heat , which in my opinion , is not good for the units. I'm working on a way to mount a shade above the units that will keep the sun's rays off the units. This is my 3 & 4 unites going back several years , 20+ , I am a Rocky Mountain Radar customer and pleased that their products.
