Fast and easy to use. Nothing to really set up. Way too fun I find my self checking my salinity a lot more including my friends. Couple of things, wish it where made of better plastic, casing feels a little week and also wish they would have included some kind of water for the price.

This is my first time owning a digital refractometer so I was a little skeptical about accuracy at first. I was relieved to find out it measured values very close to my analog refractometer. The unit automatically compensates for temperature which is great and can also be calibrated using just RO/DI water.
The great thing about this unit is that I no longer have to look like I am gazing at some distant planet, staring into a bright light source to get a salinity / SG reading for water and counting lines between number markers to get an accurate reading. It's taken the tedium out of measuring SG.

This thing is GREAT. I went a long time without one and now you can't take it from me. Thanks again for another GREAT ITEM.

this thing is seriously accurate. i had some major issues going on with my tank and i knew something was off. well i checked this against my tank and my salinity was seriously low. so much that when i adjusted it i had to readjust all my livestock. i wouldnt run 35ppt exactly as this thing will have it dead on and surely what you were using isnt this accurate.
now my tank is on its way to recovery.
