So far, works as described
I liked that it was as advertised.  I have only used it once and it worked as described.  One possible negative point is that the bag will rip if it gets too heavy for the ring to hold.  The first bag was about 2/3 full and the ring held, but not sure I could put more in.  Will have to test it with a full bag of trash and see how it does.
