Hey its true its all about the options you want do you want proximity, do you want two way communication, there are lots of things to think about. Remember this thing is protecting your baby dont trust it to anything you know. As for clifford i thought they went out of business like a year ago. Good names are code alarm, Viper, Vadar by autosecure(two way), Auto page has a good rep to. do some research and buy the product that fits what you want it to do. Good luck peace
