Query: Works fine but lacks quality construction

This machine asssembles easily and works well. Flowtron went cheap on the parts as it flimsy construction and I don't expect it to last but a couple seasons. For a few dollars more in better materials, they could have had a great machine that would last many years. The mulcher works well with oak and apple leaves. Sticks eat up the string pretty quick and often clog the machine. You are paying mostly for the idea here
