We received two compost bins totaling $400.00. The description said they were insulated, study and had air vents. Not true... they are not insulated, have funky little plastic air openeings. The plastic bins are cheaply constructed, arrived with two broken pieces, snap together in a very unstable manner. I spent a day trying to get through to the company, on hold twice for 50 minutes each time. Come on Gardener Supply you can really do better than this.
