To be honest I was hoping to get more out of these cases. They seem to load fairly quickly and I don't prefer them over the ones that come with my Delta BOSS, and they're no better than the Grizzly sleeves, which I've also tried. I've also seen others complain that they are tight and difficult to put on and take off. I can confirm this is an issue in hot weather. There is also a smaller diameter size than mine for the car. So it's just a waste. Overall I will keep looking for something better.
