Query: Not the Best Uniden Phone

I purchased this phone and was very dissappointed. I have other Uniden phones for my business that are great but this phone is terrible. When I am talking the phone goes completely dead. The batteries life is null as this happens when I pick up the phone from the charger. The coverage is also average in comparision to my other uniden. I haven't even used the answering machine or the other features as I plan to return the phone.
