Summary: I bought this unit to replace a 900MHz Uniden cordless set. We were getting a lot of interference from our baby monitor and neighbor's phones (and baby monitor). The voice quality is similar to a mobile phone, a bit "thin" and "tinny", but still very good. The phones are attractive and easy to use. I'm not a huge fan of the orange glow, but it's not a deal breaker. I don't live in a dense neighborhood, but interference was an issue, as is security.
Summary: These are the only phones I've found that don't get interference from my laptops' wireless connections. I already had one of these phones and have been looking in vain for extension headsets (they're ridiculously hard to find without having to buy another base unit), so I finally gave up and bought another base unit with one extension set.
