Doesn't clean that well
Made of cotton swabs, so they soak up paint
Review:
Sure, it's easy to use and clean the barrel with, but face it: swabs aren't that great. They can't clean out the porting, so you're kinda stuck. I would recommend getting this product as an extra with a squeegie. You can use the swab to clean out the majority of the paint splatter, then run through with your squeegie to get anything else left and clean out the porting. I think it does it's job OK, but it's not the best. Get this only if you already have a squeegie, not by itself.
Conclusion:
Not the best out there, but it works well. Buy this if you have a squeegie too, and you can use them together to clean out everything in your barrel quickly and easily. Still, the best way to get around this cleaning stuff is to buy a barrel that's designed to clean itself anyways, like J&J Ceramic.
