Review: looks great - i think a large part about aquarium review is longevity, which i cant review yet. but for the tank itself, it is very nice. the glass is clear. the whole thing looks very clean. its a nice tank and worth the premium imo.
Review: Beautiful tank! - I got the 3 gallon nano tank for my shrimp. This is a beautiful tank and the quality is excellent. It showed up well packaged and on time. I’ve wanted this tank for a long time and it did not disappoint. UNS is worth the extra money. I got the UNS glass lid with clips and it’s perfect 😍
