Title: Great product
Review: This is a great product. My sister has a habit of walking in unannounced especially when I am in the back part of my house working with my computer. This device announces her arrival every time! The only complaint I would have is that it is pretty loud even on the "low" setting and that it rings three times when it is triggered...a thin piece of foam over the front of the receiver fixed this problem nicely. This is a great product for the price.
