||Good for their price... sort of. Matrix bb's are rebranded from other bb's. They aren't the best. Even just sifting through 10 randomly selected bb's, about 3-4 had ugly lines on them as though someone cut them slightly with a knife before packaging them. The bb molding process probably wasn't the best.
If you are looking for competition grade bb's, go Madbull, G&G, or definitely above all, Airsoft Elite. Airsoft Elite bb's are made to be so precise as to have less than 2-4 fps variations per shot. They are a bit expensive but worth it for competition.
For backyard these bb's are good. Not bad at all. I used them in my UTG L96 and they do have good accuracy for the most part. The bad consistency is due to my hop up and bad positioning of inner barrel spacers.
-Accurate to an extent
-Heavy, wind doesn't affect them as much
-Lasts quite a while if you use these in sniper rifles
-Environmentally friendly if you don't want squirrels choking or anything like that lol
-Okay to Bad quality/smoothness
-Do not wash them or else you may shave them a little and reduce their size/consistency.
