I have 3 50 gallon composters and 2 80 gallon.  They are easy to use and work great.  The stands are solid and the mechanisms work great.  the 80 Gallon is all plastic on the inside so it doesn't corrode.  the 50 gallon have a closing mechanism that corrodes.  Having said that lifetime was great about replacing the one that corroded.  I simply spray the others with rust proofing paint
