Let me start by saying, this little glass feeding dish has been a lifesaver for my betta tank! No more wasted food sinking to the bottom and rotting. The suction cup holds strong (most of the time), and I love watching my fish eat right from the clear dish.
The glass construction is definitely premium - no weird plastic smells, and it's surprisingly thick. I use it daily for my shrimp colony too, and being able to monitor their food intake is super helpful. Pro tip: Use a straw to drop food in precisely!
However... that suction cup could be stronger. About 20% of the time I find it mysteriously at the bottom of the tank. And heads up - measure your tank first! At 60mm, it's slightly too large for my nano setup (totally my fault though).
One weird thing - some reviewers got plastic instead of glass? Mine was definitely glass as advertised. Maybe a quality control issue there.
Overall? For $8-10, this is way better than makeshift solutions. Just don't expect miracles from the suction if you've got determined pets (looking at you, hamster owners!). Perfect for fish and shrimp keepers who hate messy tanks.
