I had be using the 3 wheel caddies for my bigger plants, but after 2 incidences of plants tipping while rolling them (one incident costing me an expensive yucca tree!), I searched for something more stable and decided on these 5 wheel caddies.I chose the black ones, which are perfect and seem to compliment any saucer and pot without standing out visually. The tall, heavy plants are much more stable now. I only wish I had gotten these sooner. I highly recommend this 5 wheel caddy! Stay away from 3 wheels for large plants.
