I ordered the White version of these tall pot planters to coordinate with my white front porch veranda. They look great situated in a row, and are very stable on flat surface. I tried to remove the inner tray, but it was REALLY difficult, without resorting to using a tool (screwdriver). Since I didn't want to damage the inner compartment, I left the tray inside, and simply added 2-3 inch layer of small stones for better irrigation, then filled up the containers with potting soil. The added weight of the stones & soil provided further stability; the planters haven't been knocked down by strong winds (yet). The 20 year warranty is a really great selling feature, as I purchased cedar wood planters 15 years ago from a big box store, and most of them degraded within 10 years due to harse inclement weather. So pleased I discovered these planters through Wayfair!!
