Things I liked:Not much Things I would have changed:The thread on the brush heads are messed up and will not screw onto the rod at all so those are worthless, and the rod flexes a bit too much and comes lose while using it. The handle is wobbly and lose so you can't turn the rod with it as you pass it through the barrel. What others should know:Don't buy this kit!
Things I liked:The oil seems to be of good quality and am pleased with it so far. Things I would have changed:The tip broke off of the bottle very easily. Maybe keeping the tube in my gun case made it loose, but when I went to put the lid back on the whole tip broke off, and I wasn't pushing it hard at all.
