Bests & Worsts Reviews from Amazon

Yesterday I tested the tracker unit by putting it on a fence post about 100 feet away. Checking the app, it showed my location and the spot where I'd placed the tracker. Perfect. This is going to work. I put the tracker on a collar and put the collar on my cat Lewis. He seemed fine with it. This morning I let Lewis out. He was on the patio sniffing around and the tracker screen showed he was very close to me. I closed the door and went inside. I haven't seen him since. The Whistle app shows him at the same spot on the patio. Trust me, he's not there. After several tries at the 'update' button, I got a nice text message from Whistle saying they could not establish contact with Lewis. So this is what I get for trying to be a responsible pet owner. A product that has an ongoing monthly charge, but no cat. It worked in rehearsal, but not in practice. I"m returning the parts Lewis did not take with him for a refund. Buy it, don't buy it, you decide. But my cat has been missing for six hours and the device that was supposed to track his movements did not work as advertised.
