Here are some best practices: Open the collar until it clicks - then it will stay open to slide easily on and off. Find a good place to store them. Consider an alternative to the bucket as people tend to "drop" and "throw" them in and could possible damage them. If the rubber gets sticky - CHALK IT UP! If it gets dirty, clean it with a wet rag! OSO Barbell offers a 2 year warranty on the locking mechanism. These Collars are designed to take a lot of abuse when clamped on a barbell. Aluminum will bend, therefore when they are not on a bar, avoid throwing, kicking, stepping on or any other means of abuse as this will void your warranty.
