Love it and is really good but the price is too high and also takes too long to finish all the tests. They need to work better in the Marine Master to get the results faster.

The Hanna people have top notch equipment, and the best tech support!

Great

Customer service is top notch! Packed well and shipped fast!

Everything works predictably and I can count on it to measure what I care about. Thanks
