A must for reef tanks
This is so easy to use. Calibrate with rodi water. Quality is excellent, it's easy to clean. Very durable, it's speedy to use too. Have no issues with anything sticking.

Works well good value
Good value easy to use easy to read, easy to clean, seems accurate, consistent with aquarium store and specific gravity test. — I do not have a laboratory grade instrument to test against.

Good product!
I have not owned an expensive version of these to compare it to but it works fine. I calibrated with RO btw at my LFS and it’s been fine. Sometimes you need to get the light just right to read it but that may be normal considering how they work.

Easy to use and accurate!
This was easy to learn to use and is sturdy. It comes in a case that keeps it safe, clean, and organized. It’s small enough to fit into my hermit crab supplies drawer and doesn’t need any batteries/charging. Just sunlight!
