Very Disappointing for "New Technology"

I am very disappointed with Panasonic's DECT technology that supposedly will not interfere with wifi. Not true. Facts not advertised are that the baseset plugs into the phone jack and "supports" all other handsets. So none of the other handsets plug in. Sounds like a handy little feature, but don't let it fool you...no phone jack, no signal. The further away from base, things like wifi and xbox wireless render the handsets useless. No sound whatsoever and dropped calls leave you feeling like you are back in the 80's...bummer dude! Bring back the 5.8 Ghz. and plug those handsets in! Each and every time.
