Ninestars 21.1-Gallon Trash Can Liner Ring vs PTOOTP Trash Bag Fixing Ring

These are not competing trash cans. Product A is a rigid stainless-steel and ABS liner ring made for Ninestars DZT-80-4 and DZT-80-35 cans; Product B is a four-pack of thin rubber bands that stretch around any bin rim. Buy A only if you own one of those Ninestars models and the original ring is gone. Buy B if you want a cheap universal fix for bags slipping into any can. Neither is a durable part: A is a third-party copy with no written warranty, and B's rubber will stretch and crack over time.

• Choose the Ninestars replacement ring if you own a DZT-80-4 or DZT-80-35 can and want the bag held the way the original ring did.
• Choose the PTOOTP rubber rings if you have several bins of different sizes and want a flexible band that fits any of them.
