I had picked one up last year and I love it! Mine had a reasonable sensitivity to motion, and it did hesitate a second before it jumped. Like Scarrycher, I had to weigh it down with two cobblestones, one on each side due to it moving when it jumped. I don't recall any clicking sound. If you have to walk right up on yours, you may need to exchange it. The sensor may be positioned incorrectly. Exchange it at your local Spirit store for another and see how that one works.
