Konstantin Your product is very well developed, well thought out, shipped and packaged quickly and safe. I had a few problems on my half as it was my first time using Ebay but Konstantin helped me out with the best possible support. I give his service, build, and support an A+. I love the clock it is really cool if your thinking about getting a nixie tube clock I have to say do it because they really are a unique piece of history not to mention they look awesome. If I had to ever buy another tube clock or something else interesting I would defiantly buy from KOSBO.com...
