I have had my Husqvarna/Viking Designer Topaz 20 which is a sewing/embroidery machine since 2012 and it has been fantastic. The dealer gave me a deal since it was a floor model -but that told me if there were any bugs they had been found. In the 8 years I have owned it, it had one problem with the tension which he adjusted and had it back to me in less than 24 hours. I was hesitant because of the computer pad - but it keeps on working without a problem. When I took it in for general service my dealer said my machine was the cleanest machine he had seen. Told him I clean it out after every project and he said he could tell. But it is because of the QB i started doing it. People said how easy it was to clean out a machine and so now I do it with all my machines.
