I ordered the Wunderlich Ergo Screen last year from them which arrived quite quick. Then I sent it straight back as the Quality was crap. I called them (eventually got thro to a person after about 5 calls) after about three weeks and they said they had sent the replacement back to Germany and they would call me when the replacement for the replacement arrived. After about three months I called them again and was promised delivery within a couple of weeks. Anyway, I eventually received my Screen which was not perfect but what with all the hassle I accepted. Seems to me that the place is run on a shoestring if they can,t at least have someone to answer the phone. Not everyone can do business on line. By the way, my experience of N.N. is that they are not so nippy !!.
