I ordered 5000 rounds before several time but last time i ordered these, the bag seemed not full. So i poored them into a 5000 round bottle and from the looks of the empty space, it seems i paid for 5000 and got 4000.Great money-wise function perfectly with my lancer tactical airsoft gunI very picky with which bbs I run because I only use gas blow backs so I need the bbs to be extra hard as to not crack when the bb is being chambered and so far these have worked great compared to several other brands I have tried. I haven't found a single bb that was deformed or had a seam, I haven't had any of them crack while firing and the accuracy is solid. i bout .20s for my pistols and the .30s for my rifles and smgs and they work great. They seem to be much more smooth than other brands so much less friction in the barrel when firing resulting in consistent accuracy and fps. For the price these are great. Valken brand or Bulldog brand bbs are also very nice but very expensive.They work as well or better than the name brand BBs.I am an avid airsoft player and hit the field every weekend. I run a shotgun and Grenade Launcher combo which is a long way of saying i burn through bbs. So finding a source thats cheap and reliable is a must. When i saw these i was skeptical but after 6 months of use im hooked. Their cheaper then the fields and way cheaper then Evikes with out any problems of them shattering. Even when used in my high powered sniper rifle. Just what i needed.Bbs are durable don’t mess up the internals in your gun and shoots very strait, I suggest getting .30 for aeg’s sniper get .36Works great for my son's airsoft...but I sure dislike picking them up out of the carpet or vacuuming them up on accidentHave not been able to find them cheaper anywhere else. Works Perfect, we airsoft weekly
