I had the safety 1st monitors like the one pictured at left. They were so horrible I couldn't rely on them for anything! They recieved all sorts of static, and I often heard peoples phone calls on them. They would make clicking noises, and if you turned off the babys unit before you turned off your reciever it would make a horrible high pitched squeal until you turned the other one on that would surely wake up the baby. I hated these monitors and after only using them 3 times gave them away....fully warning the mother about the problems.I now have the Graco Sound Sleep monitors and they are the best ever!
