Things I liked: As this is the only hi-cap for my Cross man springer shotgun, it is not up against much. Winding is easy, and unfortunately does not come with a (winding) key. As for the quality of the product, I give a high rating.
Things I would have changed: You have to wind this product several times every magazine, will not last the entire day. A few extra bbs are left inside after the compartment is full, and you may need to turn the gun upside down in order to load those, this is good because it tells you when you need extra ammo, and automatically forces you to conserve them.
