Query: Didn't work for me

Purchased this unit (2 phone system) 3 weeks ago at W-mart for a little bit more money....needed it in a pinch. Although it has some fairly nice features for the price, it has performed poorly. Although there is no static, both phones produce an echo when the volume is raised past 50%. Friends say they also hear the echo on their end when calling me. The other problem is when the speaker phone is used, the sound cuts in and out, making it sound like a bad cell phone call. I'm on Amazon now, looking for a replacment.
