Great little tool. Well packaged. great eye piece for viewing. Dont forget to read directions on easy to do calibration.

I have the manual one when I want a good reading I always use the new it now it is very important to meet with my saltwater tank that the salt level remains the same thanks refracted and I'm glad to have it's good to be sure of what you got and I'm enjoying it

My refractometer work great thanks for the great price as well.

This Salinity Refractometer is easy to calibrate and see the results fast definitely worth the money

I had my doubts at such a low cost but was pleasantly surprised. It appears accurate and holds it's calibration. I have much more faith in this than the floating or or needle hydrometers.

I accidentally bought a refractometer used for brewing instead of aquarium/seawater use, so I bought this as a replacement and it works great. It is very easy to use and clean and comes with a pipette for adding the sample. No complaints at all.

Holy smokes. I've been using a hydrometer and my tank tank running at highhhhh. I pannicked last night. Slowly lowering salinity in reef overnight. Should have bought years ago.

👌🏻 works well, easy adjustments

Like the product very much, the focus is sharp and bright. I still don't know how it does it buy it gives the results faster the a blink of an eye and accurate. It's a major, major go
