Okay, so I've been using these Senzeal glass feeding dishes for about a month now, and here's the tea...
The good: They're STUNNING. Like seriously, the crystal clear glass makes my tank look so fancy. My shrimp actually use them (which is rare for picky eaters), and cleanup is stupid easy - just a quick wipe.
The bad: Those suction cups? Girl... One stays put like it's glued with superpower, while its twin acts like it's allergic to glass. My betta thinks the wobbly one is his personal hammock though, so silver lining?
Pro tip: If you're buying for reptiles or heavy feeders, maybe look elsewhere. But for shrimp/snails? Worth the $10 gamble. Just don't be shocked when you have to MacGyver some solutions.
P.S. To the reviewer whose gerbils ate the suction cups - I have SO many questions.
