I received this product as a baby shower gift for my first child in 2006. I am still using the same product now in 2013 for my second child. Very pleased with how long the product has lasted. We use it every day to watch my baby nap and sleep at night. After using this I am not sure I could go without a video monitor, lol. Before my second child, it was still in my son's room at age 5 for us to keep an eye on him. Sound/Video Clarity It does get staticy quite often. I have to have it sitting a certain way to help prevent that issue. I can always pick it up and get it ok if I need too, but the way it has to sit on my night stand is not in good view but it is where it keeps it from having static and white noise. Interference I do have issues with static when it is near remotes, ipads, iphones and other like things. Durability This product has held up amazingly over the last 7.5 years. We still use it with our second child. Portability I have used it clipped to my pants while outside doing yard work. I do like that I can move it around the house with me so I can always keep an eye on my baby.
