Query: WATCH OUT! The green monitor is an old model that doesn't work!!

I own a blue Summer Infant monitor and it is great! The picture is clear and interference is very rare. The built in sound monitor picks up everything, including my baby's breathing. Much better than smaller more portable screens since I can leave it on a shelf and see it from anywhere in the room. When I wanted a second monitor I ordered the green one because of the price. Once I received it I realized that it is an older model and it was terrible. I couldn't get a picture even just a few rooms away in my house. When I did get a picture it was impossible to see what was going on. It also wouldn't work with my blue system. I could have received a faulty one, but I suggest paying the extra to get the newer, blue model.
