Query: Non functional unit - 0 stars

I was excited to receive this item. As I set up to do some quick electronic repairs, I took it out of the box. Plugged it in and set it to 700 degrees Farenheit.The base turns on but the iron does not heat up. Nothing, nada, arrrgh! I had to use my 7 dollar Sears iron which has been working for the last 6 years!I am not happy at all and probably will not go Weller ever again. Although the merchant promised to ship me another one right away, I am a bit skeptical on the quality of this digital unit.
