expensive LNB's clearly equal (unfortunately very short life)

Since my old Quad LNB had given up the ghost after 10 years, I was looking for a replacement. In this I found one that received values ​​are its more expensive to some previous par and in order (ASTRA). The assembly (Technisat aluminum reflector) was simple, the weather protection and the housing make a good impression. Using the life (hopefully) decide in the coming years.

Addendum:

In less than 2 years of operation can receive power drastically and the LNB had to allow for another (HUMAX), which proper reception, to be replaced. The quality is unfortunately not seem designed for continuous.
