Negative Positive
Title: When it works, it works fine, but...
Review: I read many glowing reviews on this product before purchasing and in fact was impressed with the way it did work. Unfortunately it kept getting stuck which defeated the purpose of a device that functioned without constant intervention. I would come home from a day's 12 hour shift and find the unit non-functional and my cats with their legs crossed. I do have 2 cats and they tended to trigger it frequently in play. I ended up sending it back and did get a full refund after trying it for 6 weeks.
Is the review positive or negative?
