  1. Mike Nick

    Why mess about with 4 individual displays when this device makes life much simpler and a very good price.

  2. Mike Nicho

    Wiring 4 individual & seg displays together is now a thing of the past. These displays (I have used the white and the red) are so easy to use and at just over a quid each, they are an amazing bargain.
