I have this one and like it very much. I would suggest getting a larger bottle of ‘7.0 Standard Reference Solution’ too.

Those work too, but they require a lot more frequent calibration. I was having to calibrate once a week when I was using it. If you do go that route, make sure to buy some extra calibration buffing crystals. The ones that come with it don’t last long. My apera only needs calibrating once or twice a grow.
