Yep, the first batch. Unfortunately it's a big batch, because the Chinese factory sent testers to retailers everywhere in the world and those were unbelievably great, so everyone ordered a lot of it. Then they sent those crappy ones.
My sources are a webshop that mainly sells BBs and an other airsoft shop owner.
BB king, Nuprol, Rockets and a couple of small brands are the rebrands of these.
