iTouchless Oval Trash Can Retaining Ring vs Ninestars 21.1-Gallon Trash Can Liner Ring

Both are replacement bag retainer rings, not trash cans, so the right pick is the one that fits your can. The iTouchless ring is a genuine OEM part for the ITOS13B and ITOS13M oval cans, and its 4.9 rating from 88 owners backs up the fit. The Ninestars-compatible ring is a third-party part for 21.1-gallon DZT-80-4 and DZT-80-35 cans, and its listing carries no written warranty. Buy the ring that matches your can's brand and model, not the one with better specs.

• Choose the iTouchless ring if you own an ITOS13B or ITOS13M oval sensor can and want the factory part that seats the lid and holds the bag.
• Choose the Ninestars-compatible ring if you own a 21.1-gallon DZT-80-4 or DZT-80-35 can and the original ring is missing or worn out.
