Review on 🦎 WACOOL Magnetic Gecko Ledge: A Versatile Acrylic Feeding Solution for Geckos, Iguanas, Chameleons, and More by Carmen Rosean

The magnets hold well and my geckos wouldn't pull them off (but they are very small sorrow geckos). The shells are small in their place, which can be a downside. Make sure the food doesn't splatter all over the place when you take out the bowl. I learned that the hard way the first time. But the smell also means they won't knock it out themselves, so that's fine if you're careful.
