Skype phone is of horrible quality

As we don't have a land line, we bought a cheap Skype phone, the Think Xtra Xtender Dual DECT phone. It was the cheapest I could find. This is a consumer product of a quality that I didn't know existed anymore. Or in other words: a horrible product. The numeric keypad only works partially. So we're returning it. Hopefully we get a full restitution.
