Love it bought the whole kit.
Don't know what I'd do without it
Love this thing, just picked up the new dKH version. Finally no dealing with color matching.
No more color matching and highly accurate (and priced).
Loving it! No more color comparisons!
Great product. Takes out the guess work about color change

The best device for testing alkalinity. Definitely a must for any reef keeper, I'm using mine every week.
Fast to use, no guessing. always use this and my salifert to double check though.
