Query: Loud noise

This monitor worked ok at first but it has increasingly gotten louder and louder in terms of static. It started out that it had to sit in a few certain places around the house and it would be ok but now nowhere we sit it is it ok! My mom got one too for when she baby sits and one of her receivers completely stopped working and the one that does is doing the same thing. I would not recommend this if you want to use them longer than 1 year. My son is 14 months and I am getting a new one.
