    Was a bit surprised it only supports seven digit entries. Otherwise the kit went together quickly and easily. It was a no-brainer. The resistor color band “decoding” is a neat feature. This thing really appeals to my inner nerd.

    works as advertised, Would probably take an amature a few hours, I knocked it out start to finish in 1-1/2 hours with a few distractions and without downloading the instructions. I used 2032 batteries and they work fine the instructions the amazon website cite other batteries but anything 3v with right diameter is fine. One thing, the paper instructions say if I multiply 5 x 6 I should get 25 I may have missed a step because it reads out 30 instead :P LOL
