Good: The ring grips the rim of a standard 5/6/7 gallon paint can securely. to start, tends to kink the threads and requires many turns after proper engagement. Ugliness: This doesn't work with Home Depot's cheap orange buckets, which have custom lips, making this a full HD bug. The issue can be resolved by redesigning the product to use multiple (2/3/4) concentric steps. With four threads, it only takes an average of 3/8 turns (135Β°) to turn the cap: 1/8 turn back to engage the threads and 1/4 turn forward to tighten the cap.
