Probably the cheapest BBs, and since they are the cheapest, the quality matches; the BBs have a lot of air inside, which leads to low shot consistency. The BBs are also not precise: if you have a tight barrel, they will wear it out and make it crooked, because not all BBs pass through, and worse, sometimes they block the barrel and start accumulating and breaking apart inside. The hop-up works differently with each BB, and it can also detach and break the hop-up rubber. Where they perform well is in grenades and anything that doesn’t require precision. However, I strongly advise against using them in airsoft guns as the damage they do in the long term is not worth it. It’s better to pay about 20 PLN more for precision BBs.
