Query: Great Big Disappointment

I only gave it one star because there isn't a minus 10-star rating! Poor reception, voice quality is worse than an analog cell phone, range is limited (doesn't even work upstairs), and probably the worst customer service I have ever experienced from a company. Do I need say more? DO NOT BUY THIS PHONE (or any Siemans phone for that matter) unless you enjoy being slowly tortured!!!
