Bests & Worsts Reviews from Amazon

Just a heads up, make sure you read the most recent reviews. Amazon likes to stack their good reviews at the top, so I purchased this thinking it had all great reviews, however most of the recent reviews are negative. I only noticed this after I got the item and it did not work. I tried testing the thing several different times and the alarm went off once and did not go off again. However, it did go off at random a few times, and the wheels never moved. I wouldn’t waste $40 on this product. I wish I had read more reviews on it before purchasing, because most people are having the same problem.
