Just got this intake guard for my UNS 30A shrimp tank and here's the tea ☕️
First off, it DOES work - no more worrying about my baby shrimplets getting vacuumed into the filter (RIP little guys from before I bought this). The slots are perfectly sized to keep even the tiniest critters safe.
Installation was stupid easy - literally just pops right into place. Fits all the UNS Dual AIO models like they claim. The low-profile design doesn't ruin my tank's clean rimless aesthetic either.
BUT... $20 for a tiny piece of plastic? Really UNS? I get that it's specialized equipment but c'mon now. Also noticed it moves around a bit if you're doing maintenance, and you can't fully close the filter top with it installed.
Verdict: If you're breeding expensive shrimp/critters, worth it despite the price. For casual fish keepers? Probably skip unless your fish are suicidal swimmers.
