Summary: I purchased this phone because it uses lithium ion batteries, which are the best. Unfortunately, the phone would not power on, even after charging it for several days. Returned it for a refund. Apparently, I am not alone in this experience.
Summary: I got a defective unit, so I called Uniden customer service. I've never been treated more rudely by customer "service" in my life. They refused to help me without my home phone number (I don't give it out- that's why it's called "unlisted") and they bascially told me it was *my* fault that the phone wouldn't even power on. (even though I'd charged it for 24 hours). Then I called the seller- what a different experience. WestCoastMall.net was professional and courteous.
Summary: I bought this system when it first came out and never have I spent more on a phone. I bought the DMX778 plus 2 of the satellite units. The caller ID has NEVER worked, and customer service NEVER helped. They were very adept at giving me the run-around though. The quality is so poor that whomever I am speaking with gets static. No matter how I adjust the sound, I can never hear very well either.
