I really appreciate the people that i've interacted with in the past, this time things went fairly well considering how covid has affected everything. i really want to thank everybody at Hanna Instruments for keeping everything happening in a timely manner, shipping packaging was great everything arrived intact.

Quick delivery and works perfect. Thanks

A good product, only wish is that it had 2-point calibration.

Cap does not seal well enough to contain storage fluid from working out

Hanna ma(es the best hobby grade checkers available for the reef keeping community. Would highly recommend for anyone getting started in the hobby... wish I had invested in a set checkers instead of spending money on other test kits in the past.
