Perfect set, it is a little bit hard to assemble the case, but it is a relief that everything works as it should be. Much better than for example from PVElectronics which dont deliver according to assembly instructions and price much higher.
This is a truly beautiful creation. I love Nixie tubes, but the high voltage and the aging problems keep me from owning any. If you could come up with a means of mass production I think you could sell this as a finished art object for more money.
I am very impressed with the clever design. This is my favorite clock, and I tell you, I have some really clever round LED clocks, etc.
Minor things. The adhesive leaves a residue that really should be washed off somehow. I didn't do it. I would increase the thickness of the digits a bit. Oh, the round part of the sixes broke the tiny attachment and fell out on two of them. I could put them back perfectly so it is no problem at all. The film protecting the rear side of the digits is hard to remove. It just takes time. I am thrilled with this clock!
