If you hate filter maintenance and much as I do you will love these. They work great without any noticeable decrease in power. The skin takes about 3 minutes to install
I use the skin until it is dirty, remove it, put a second skin on until it is dirty, remove it then let the filter get dirty and toss it.
I now change filters between 6 - 9 hours of use and have a spotless intake track. This is 3X longer than without using skins.
They more than pay for themselves in time spent.
