It sounds like a good idea in concept...but it's not something that will actually make the kids stay put. Honestly, I wouldn't waste the money on it. I personally don't allow my kids to get out of the car until I am ready to walk and when we return to the car they are put in it right away. They are all trained to get right in the car seats and wait to be strapped in. Sometimes they play around but I'd rather them push buttons on the dash then get ran over. I then put the stuff in the car. There really is no reason for kids to be standing around in a parking lot. It's just an accident waiting to happen. Good luck!
