Query: DO NOT BUY THIS PRODUCT

This product was a replacement for the other Safety 1st monitor that broke. I got it in February and about 3 weeks ago the sound doesn't work until you hit the top of it and now the on button has to be pushed several times before it goes on. To top it off, the Safety 1st company is doing nothing for me. Talk about good consumer relations! They said my warranty ran out from my first product that broke. Which by the way I mailed back to them at my expense! What a bunch of bull! Please do not waste your money. I will never buy a product from Safety 1st again!
