I have only had the Lifetime dual composter 50 Gallon for about 2 years now and it has done a pretty good job of making compost for the garden. However the latching mechanism on the left side which is the most used side has rusted so bad that we do not use it because we cannot open it. Also one of the corner pieces popped out at some point and was not noticed immediately to be replaced so there is about a 2" hole on the corner where the compost falls out when we tumble the compost. Also be careful if you need to move the unit for any reason, the plastic feet will pop off and get lost if you do not see it happen, we have lost 3 of them so far, thinking that we may just take the last one off so they match. We have one of the 80gal units also and have no issues with it so far.
