I have the machine since July 2011. Now she has given up the ghost and I had to send it for repair to Berlin. The seller, the Fa. Müller in Berlin, manages not to send me information on what now is the matter with my Topomatic. Conclusion: A great device, but a bad seller, the apparently not interested in it especially as we proceed with a customer. Next time I'll buy my Topomatic certainly no longer about the Fa. Müller.
