Remanufactured Panasonic KX-TG5438S 5.8 GHz DSS Cordless Phone with Answering System and Shock/Splash-Resistant Handset (Silver)

I use to have a problem with the microwave interferring with the phone (2.4mhz) but this phone doesn't even crackle when it is on. It's also easy to setup.

I've had this phone for over a year now, and I have yet to have any issues with it. Buying refurbished is enough to make anyone a little nervous, but everything, from battery life, to volume, to interference has been just perfect. Give it a try.
