Had some trouble getting the manual and I don't think GPS is working, but otherwise it works and looks great.
The first thing I received was defective....... When I contacted the seller, I received a quick response from the seller saying "I Will ship another circuit". Therefore, I had to transplant the Nixie tube to another circuit by myself. Transplanting was very difficult. The Nixie tube could not be removed with a normal soldering iron, solder sucking wire or solder sucking device. (require of type of integrated soldering iron and solder sucking device.) Packing and shipping are very polite and very quick. good seller. But please strengthen the inspection in the future.
