    PRO-SE CO2 Dual Stage Regulator with Solenoid.

    I upgraded from one I bought about 4 years ago.
    Great piece of kit. Spend a little time getting it set up - put it on a 24hr timer and leave it to do its job.

    My 1st CO2 regulator and it would appear to be a very good choice, easy to set up and so far working very well with no problems.
    Only gave 4 stars due to a few small wrench marks on the regulator just below the working pressure gauge.
