My experience with these tree rings is that they last for decades. They are made from good quality steel and they are thick enough to resist crushing by lawn mowers.
These are designed for a 3-foot circle and will not make an even, continuous 5-foot circle. The arc is wrong and even with additional sections, they do not simply bend to make a larger circle. I purchased 5 sections to make a 5-foot circle but they were unusable at that diameter. Other than that, they seemed solid and well-made.
Easy assemply, quick to install and keeps the mulch around the tree and out of the yard! Definetly recommend this product to dress up your landscaping.
BUYER BEWARE! When I purchased this product, I assumed (we all know the saying there) for $10.49 you received a kit and could choose what to use out of the kit to form a 3', 4', or 5' circle around the tree. However, if you buy just one that only forms 1/3 of a 3' circle, which would do absoulutely nothing for you. Therefore you have to purchase three to make one 3' circle! After rereading more carefully I see they have all the proper wording and it was my mistake. However, AMLeonard, I believe it would be much more consumer friendly to just write 3'=$31.47 4'=$41.96 5'=$52.45 and write discounted bulk buying amounts as well. Don't get me wrong though people, the quality of this prodcut is second to none. In the end it was my fault, but I think AM could do a better job of simplifying things.
