does anyone have one of these - any feedback on how it's working for ya?
looks promising - based on the cost, it's about the same as a refractometer, but not needing any light or little droplets of water, or a dunk in the tank (like a hydrometer)!

Most will find it easier using it in a glass/cup of water, which will require dunking. I have only experienced the Hanna ph pen and I found it to be testy (no pun intended), but fair enough. I recently bought a refractometer and found it very easy to use, easier than a hydrometer, it is also supposed to be the most accurate instrument for measuring salinity.
