I bought smaller dollies from Amazon a couple of years ago: they were the largest I could find and were slightly cheaper than this, but the wheels soon seize up or break off and they didn't run particularly smoothly, even when new.These drum dollies are far, far better and feel very tough. They are fine for my large half whisky barrel containers planted with various shrubs. With soil and plants they are very hard to push around the patio without dollies. Mounted on these they can be moved easily, including over the gaps in the paving. I now have an adjustable planting scheme on the patio! Ideal to track the sun or move plants to where we are sat. You can get them cheaper elsewhere, though.Highly recommended.
