So far so good , have been using it for over 3 months now and it works perfect!

I hope I calibrated it right. I can see it.

I have been wanting to get one of these for my Marine Aquarium for awhile. I Have been using those Hydrometers for over a year. Each Hydrometer always gave a different reading. Finnally decided to order this one because it had a positive review from someone who seemed to be a professional. I got it and checked the calibration and it was already spot on. Seems to be working great especially for the price!

Easy to use. Easy to read. Just move the eyepiece dial to get a clear reading.

Accurate and clear. I don't care for the storage container. It's difficult to open the latch and even after weekly use for 2 months it's not loosened, but I continue to use it because it is foam encased and keeps it at tip top shape. (Especially with curious toddlers running rampant.)
