The Max Air is top !! In this vessel the compost bags remain ventilated and does not tear when you then have to take out! The aerating the waste begins to dry yourself. Since I use this system to me this foul-smelling fluid is spared, must bring out the rubbish and completely wash out the nasty bucket then before reuse not including bucket. The bags are supplied class- price-performance ratio completely. No bad smell from the trash bin clean solution!
