My home has radiant floors so I can't put plants on them (too much heat). With 4 rather than three wheels, this caddy is well built, and moves easily on a hard wood floor. The sturdy plastic tray is molded to the shape of the frame so if it breaks could be hard to replace but could use commonly available plastic saucers - just not as attractive..
I ordered this caddy; but I received a very large pot instead. Makes me wonder about Overstock.com's shipping efficiency. Too bad. I will use the pot; but it isn't worth the amount I paid for the caddy. You ask, why didn't I return it????? Too much trouble for a very large pot.
