Considering buying one...is it worth it or should I just stick with the refractometer?

Is it worth it? No. Is it nice to have, yes.
Find it used and it won't be too bad. In my last 24hrs my ppt read 34.4 to a 34.6 swing which isn't bad at all. My calibration was easy but I've heard stories of it being very difficult (I run two temp sensors, I think that plays a factor). My probe is dead on with my refractometer.

Neptune is just for a close number. I just figure my Neptune is a very expensive timer. Either way, I'm not to big on numbers. I just watch my corals.
Needless to say. I'd say not worth it. I wouldn't call it scientific either.

Sounds like micro bubble get in the probe and when released the number comes back.

Just sounds like an overpriced paper weight that many of us bought into. Neptune has that everyone's doing it thing going for it right now. That's why they were able to get close to a thousand per unit.
Neptune is much like my experience with ford. Fords response to my lemon,"it shows there is a problem, doesn't show what it is or how to fix it." They said they could do nothing for me. The brand new lariat with 30,000 miles started shutting down on me.
Neptune had the same response, when problems on very new products happened.
To me if you want to chase numbers I'd go with Milwaukee.
Sorry just not a huge fan of the Neptune garbage

As others have said, I use my Apex Salinity probe purely as a secondary gauge. I would not buy it again given the chance. The only way I was able to get mine to calibrate correctly was to verify my tank salinity was 53000, then calibrate in the tank. It never worked for me using the calibration fluids.
I've tried standard refractometers, digital refractometers, pinpoint, etc. The only thing I truly trust is my Tropic Marin High Precision Hydrometer.

If you're in the apex ecosystem then it's one of the more useful probes imo. Just take it with a grain of salt, and if it is drifting confirm with a calibrated refractometer.
Mine just drifted on my when I moved the location of the probe. It dropped a couple points, and then a week later, it came back on its own.

I had a hard time calibrating mine initially, but eventually got it dialed in with a separate reference solution (Pinpoint). Worked for a few months, and then I upgraded tanks. When I tried to set it up in the new tank, it couldn't be calibrated, either in various standards, or in the tank itself. I asked Neptune for support but they just kept giving me more trouble-shooting tests to do at home via email exchanges, which didn't ever make any progress. So I gave up. I've been waiting for a day I have hours free to waste on it and not already frustrated to look at it again.
So no, I wouldn't recommend it.
