I see people ripping on these but once you do this one simple trick, it will work perfect and won't jam on you... Lube some BBs up before putting some in there. I always clean and lube my ammo with a tiny amount of Napier Power Pellet lube. I would suggest lubbing BBs with Pellgunoil for a substitute only to "lube in" your speedloader. It don't take long for the thing to get lubed-up and it works like a charm.
