Calcium checkers

[MyR6Rocks]

I wanted to get reviews here for the Hanna calcium checker. I'm fairly new to reef set ups & am tired of counting drops, and I'm thinking there's gotta be a better way. Looking online there seems to be mixed reviews, so anyone own one? Easy to use? Would you recommend it? Thanks in advance

I can't speak for the calcium checker, but I do have a phosphate checker, and it's awesome..... Only concern you may want to consider (if you care) is that the reagent refills are about $21+shipping for 25 tests at BRS. So if it's a test you run a LOT, the cost is going to add up at over a buck per test.
