Things I liked: these bbs shoot farther than most i have used they are better than ksc ones and out of the 5000 bbs not one was mis formed and not one jammed or broke in my echo1 m4 spc
Things I would have changed: the color black is not the best color to get you shoot alot more because of the fact you cannot see these at all.
What others should know: get a couple bags and put some silicone lube on them there not that polished.
Things I liked: very fast charge....and really good if you have a 4200mih battery charges take about 8 hours
Things I would have changed: nothing
What others should know: don't over charge
