I loved my NI-14 so much, I bought a second one, only this time I bought the bigger NI-18 !!!!! These are so awesome, and a whole bunch of built in subtle features that makes it well worth the price. Thanks Roman !!! I'm in Arizona and it comes all the way from Kyiv, boxed very well, and arrives really pretty quickly for how far it has to travel. I love my Nixie tube Clock!!!! PS: Hard to capture all the tubs on my iPhone for some reason, but let me assure you... ALL of those tubes are lit up right now.

I love this!I knew it would be cool but it’s Uber cool and funky. As the time changes the colours slowly fade from one to another. Am saving up for a bigger one for my conservatory/lounge.
