The device does not measure salinity correctly. Three of my snails and one coral died because i trusted this instrument. When i went to the pet store looking for answers, they told me the salinity was 1.040, not 1.025 as this refractometer showed. I’m including photos as proof, comparing my new refractometer with this one.
very good, perfect!!!
Just as the seller shows it. It needs to be tested, but I know friends who use it and it works perfectly, I always allow for a margin of error of 0.02-0.04.
An excellent device
It seems good
measures perfectly
The rubber part that touches the eye has white powder on it (rubber softener?).
My eyes are stinging and uncomfortable. It's difficult to recommend.
The measured values do not correspond to what was detected by the salinity reading strips.
It works well
Excellent item. Perfect service, fast shipping, and good packing .
Thank you very much, it arrived quickly, the seller is great, I highly recommend buying from him.
It arrived, but I haven't used it yet.
Everything Correct
Perfect 👍.
I see that it's a good product compared to the price, not professional but still a good product, thank you .....
Fast shipping, product matches the description and seems to work correctly, overall satisfactory.
top-notch tracking and communication
Everything is cool.
Everything arrived in good condition. I opened the package and tried to use it, but i can’t see anything and it barely moves from its position. I almost killed my fish because of this meter. It does not work properly — it shows around 1.000 salinity instead of 1.026, which was in the water. I do not recommend this product at all; it does not work.

EXCELLENT
It looks of very good quality although it needs to be tested.
Perfect. Works very well 👍.
It works, shows the salinity of the water correctly, and very fast delivery.
Very nice recieved it quickly hasn't had a chance to try it out yet
The rigid packaging as indicated in the description was not present.
Everything is okay, perfect.
The item works, but it is particularly difficult to read the numbers, I think there is something obstructing the view, maybe dirt between the lens and the glass or maybe the lens has a problem, it works anyway.
Thanks, works great.
