The dog chewed one of my ear cushions so I purchased the maintanence kit. You need to make sure that you get the right kit for your style of ear muffs. The best way is to look at the photos to match up the ear cup style. The maintenance kit is very easy to install and my ear muffs are like new again.
Pros: Easy to install
