I was In Dusseldorf for an exhibition in June 2019- from the US. Unbelievably my hard drive on my laptop crashed on the first day I arrived. I was in a mild panic as I had planned to spend 2 additional weeks in Europe for vacation and I could not be without my laptop. I googled for a computer repair place and Comstu had a good rating, so I gave it a shot. Frank was excellent on all levels- he jumped right at it and installed a new hard drive and then was extremely patient to migrate the new hard drive from German to English. He's super bright, patient and a very good guy as well. He charged a very fair rate for his great effort. I highly recommend Frank and his repair shop to anyone. read more
