This is yet another great product from GE. You must own the base station for it to work. Easy hookup and eady to use. No problems for me at all. My only wish is that they would come up with a way to transfer the exsisting stored memory to the new phone without having to redo it. It's also hard to make all phones identical in stored memory since each phone is independent. I own another brand too and its the same way. Overall happy with my purchase and would buy it again.
