These bbs are great for their actual price, it's 15 bucks for a 5000 pack of really awesome bbs. No jams or double feeds so far, and the accuracy at 120 feet is great with my G&G GR16. No stray shots to the right,left, up, or down. It's a little weird that these things still shoot accurately at 450 fps at 140-150 feet, even though they're 0.20 grams, but that definitely isn't a con. The bbs have no visible lines or seams, and i have NOT found 1 imperfect bb in the bag. They are also very polished, it's like a little black mirror in your hand. These are definitely good bbs, I'll be buying some more of these, and you should as well.
NOTE: These are not the bbs to get if you want to get your hop up adjusted. These are very hard to see in flight, which is what they are meant for. Tracers work both ways, so go with these if you don't want to be spotted or tracked. If you buy these, don't complain about not being able to see them. THEY'RE BLACK!
-No visible lines or seams
-Very hard to see during the day (good thing)
-Does not mark up your barrel
-No jams or misfeeds
- Doesn't come in a container with a loading nozzle (well, who wants a huge container though?)
Nothing else besides that, but even then that one con doesn't even matter.
Scratch that con out,
