I have two of his new style with the removable covers. They work great, the only real issue I have is getting the cover off, those rare earth magnets he uses really like one another! I think he needs to add a slight indent at each end for better grip, but that may be just me. Otherwise they function perfectly, hold longer ammo and certainly aren't going to come apart in the field! I also like you can choose your color. They are clearly marked with the caliber on the top, but keeping the color consistent with each caliber makes it real easy to grab the right caliber from the range bag is you're shooting more than one caliber airgun.
