Let me start by saying - these little clips are GENIUS in theory. The transparent design blends into my aquarium, and the suction cups actually stick surprisingly well to glass (pro tip: wet them first!). I use them daily to hold nori sheets for my tangs, and they do keep the seaweed neatly in place.

BUT here's the hilarious flaw - these things FLOAT like they're made of helium! First time I dropped one in the tank, it shot back up like a fishing bobber. My fish looked as confused as I was. I ended up supergluing small flat rocks to the base (not pretty, but effective).

The build quality feels decent for the price - no sharp edges, and they haven't discolored after months of use. While marketed for decor too, they're really only strong enough for lightweight plants or thin food sheets.

Final verdict? 3.5/5 stars. They work once modified, but manufacturers should really add some weight to the design. Great concept that just needs one practical tweak!
