Things I liked: Magazines work well in my Super 8. I bought 2 so that I can reload easily for target practice. I like that the magazine holds 25 BBs.
Things I would have changed: Make it easier to see the tiny arrow to hold and release BBs. I marked mine with a silver sharpie and that helps a lot!
What others should know: These are different from the magazine that comes with the rifle in that the hole to put in the BBs is on the side rather than at the spring lever. Took a while for me to find it.
