So right Jill! We've learned the hard way. You hear the "click" and know you've been had.
Coffee doesn't stay in the mug very well when you are running.
The other thing that makes them so good is they are totally adjustable. You can guard a narrow section or almost a full circle and with 30ft reach that's an area 60ft side to side. Day, night or always. I don't own any part of the company, this is just one of the best things I've purchased for the garden. I can sleep at night and not have to run out every time one of our property motion sensors goes off. We won't think about the night I ran down into the garden only to step around a tall phlox right into the face of a skunk. Glad it was his face and not the other end!
