The results compare directly to Salifert and API. The accuracy and consistency seem very good. Make sure you measure 1.0 ml of the reagent and keep the vial clean when done. Rinse with RODI each time and store vial inverted to dry. Simple and quick.

Never was accurate, even after replacing the calibration fluid. I mean it was so far off it almost killed my tank.

This is a great checker. The digital read out is really nice. So much better than counts drops and shaking like the Red Sea kit.

Now this it a tester I like. the only way it could be easier would be if it was a probe. I made the mistake of ordering the ppm tester when I wanted the dKH one, but in the package has a sheet that has the multiplier to go from ppm to dKH so no biggy.
Pluses and Minuses By John on 5/16/2016

Pluses - Easy and fun to use, which means I'm testing more; it's accurate.
Minuses - You have to manually do the conversion to DKH or meq/L, which seems odd for an electronic device. The box is comes in is funky and not designed well. It's not as fast as some say, but still easier and faster than a Red Sea type tester. The instruction manual is simple to understand, but a little weak on information.
The best…..when it works By Mcmullen on 4/8/2016

So this is easily the best Alk checker when Hannah has their reagent working properly. Sometime in Novemeber 2015 (maybe sooner) they changed packaging so that when the liquid reagent encounters the bottle lid, it somehow deactivates the reagent. This was addressed, and supposedly fixed! Well, guess what? Still same problem!! I finally ordered a "Salifert" kit and my Alk level tested higher than the max level…..the max is 15.8! I kept dosing Alk based on my Hannah reading low levels. For those of you that do not know, anything higher than 12 is high for Alk, and my tank runs about 9. This is a sps killer. I do believe Hannah will fix the problem but how can you trust the product. I'll constantly be double checking!! I cannot recommend at this time!!!
Excellent and easy to read. By DAVID on 4/3/2016

I find this one easier than API or Red Sea to read. I just made a ALK Table with the reading and dkh. So all I have to do is look at my chart.

This is very easy to use and is accurate. Kind of pricey but well worth it.
