Honestly not worth its price, but I splurged because I wanted one. Definitely enjoyable to look through! Would rather build my own for $10. Haha but it does what its advertised to

I love this thing! So does my cat.

Love that the magnet goes inside the tank.”

Professional tool, great material.

Good stuff

Best $30 Ive spent on the reef. Absolute game changer and helps you appreciate your corals so much more. Easily transverse corners on a Biocube 32. Highly recommended.

Wifes first comment was best purchase ever for viewer with orange filter. Family enjoys seeing fish in more detail, I enjoy being able to diagnose coral in more detail. Worth the money.

Es un poco costoso para lo que es, pero me alegro de haberlo comprado porque las visitas se entretienen con la lupa, al igual que lo hago yo

OMG I never realized what I was missing!!! I ordered the 5 inch. As you can see in the picture I posted, the size of the 5 inch laying on a magazine to put it in perspective. The magnet is plenty strong to hold it in place, the magnification from the front of my tank to the back is perfect! The details I can see thru the flipper are astonishing. Im a 30 + year marine aquarium hobbyist and with the flipper Im seeing my corals, invertebrates and fish in a whole new light, not to mention all of the tinyist of life I have been missing but now can see. If you want to see your marine environment like its the first time ever, look at it thru a flipper magnifying lenz!! You wont be disappointed as the what is that? wow oh wow hunnie come look at this! and many other reactions begin to flow!!!

Works great. Good size.
