It is kind of old, 3-4 years and I haven't used it in awhile so really can't attest to the accuracy of it but aesthetically it's in okay condition. The only thing really wrong with it is that the two metal connections in the setup have corrosion/salt creep on them. One is where the electrode locks into controller and the other is where you plug in the CO2 hose to the valve.

Here are the pictures I have of it. The things in the photo's on the left are some sets of chords for a multicontroller and a photocell just to let you know.
