Easy assembly, very stable and robust feeling. When doing the double wheels make sure you use the correct axle brackets -- the ones with the indents should be stored for later use if conversion ever desired. Cotter pins and washers missing -- customer support supplied info regarding specs on same so picked up at local hardware for 1/2 buck. Almost too pretty to use but I expect it will soon be a valued tool even if it is dented in spots and I promise to clean carefully after mixing mortar and concrete. May also serve as bed when am on the outs with the little lady.
