Every kit comes compete with highly detailed assembly instructions. Every kit and assembled product also comes complete with highly detailed operation guides and background notes.
We do stuff differently here at MrNixie. I am not happy until you are happy. If you have bought a nixie clock in kit form, in the unlikely event that you hit a build problem I am only an email away. I believe that what you are buying is much more than just a bag of bits. I will support you before, during and after your purchase (whether you choose a kit or assembled product).
I guarantee my kits to be complete and free from component defects for a period of 90 days. I guarantee assembled products against faulty materials or workmanship for a period of six months.
If you need me, I am just an email away.
