As a Grandparent starting all over raising children again I was looking for smthing that I could trust to keep after the babies and still be abl to get my work done. Thats when I went with the Fisher Price Long Range 900 Mhz monitor with duel receivers. Fist of all Fisher Price is a name which I TRUST and grew up with myself, second it was a long range set whitch was great for me because then I can still do all my gardening and yard work and still hear the kids when they are put down for a nap. I also found that you could add more receivers to the Fisher Price Long Range 900 mhz Monitoor system....
