A glowing review
This is a beautiful, hand-crafted Nixie Tube clock made in the Ukraine.  It is built on a transparent, acrylic base that shows off the electronic circuitry inside.  Other versions are available with a wooden base, but I particularly like the retro, high tech look of this design.  The circuit board is beautifully-crafted and assembled.  The whole effect is very engaging, and there is depth and a sense of motion to the Nixie numerals unlike other kinds of digital clocks.  The vintage Soviet-era tubes (some with "CCCP" visible on the back) glow with a lovely warm orange.  They are soldered to the printed circuit board, so they are not too-easily replaceable.  The manufacturer claims that the Nixies are operated at lower than maximum brightness so that they will last for many years.  The digits simply change: unlike some other Nixie clocks, there is no "roulette" effect between numbers although there is a routine to evenly-activate the digits between 1 and 4 AM to prolog tube life.<br /><br />The clock is powered by a USB power adapter and cord (included).  It is easily programmed with two buttons.  There is a temperature sensor that plugs into the back of the base to measure room temperature.  The battery backup uses a small CR1220 coin cell (included) - the clock turned on keeping perfect time when delivered!<br /><br />The clock displays 12 or 24 hour time.  Once a minute, the clock can display the room temperature (preset for deg F for the US), and this is a very nice feature.  The date as DD.MM.YY or MM.DD.YY can also be displayed once a minute.  These options can be turned on or off in the menu.  Blue LEDs under the tubes and a subtle hourly beep (from 7h00 - 21h00) can also be turned on or off.  There is no wake-up alarm, but that's not important to me as this is a desktop or table top decorative clock.<br /><br />I am very pleased with this clock, and happy to recommend it highly.  It is a unique timepiece with a unique and interesting provenance.
