This is, by far, the BEST squeegee I have ever used. I don't like the redz swab kit because it leaves tons of little fuzzies in the barrel, especially if you have lots of porting like me. This one is cheaper, and holds up. This swab has given me a mirror finish on the inside of my barrel every time. I DEFINITLEY RECCOMEND THIS PRODUCT! I didn't think it was gonna be good because it was so cheap but it's great. Go buy one. Now.
Buy it, because it cleans best, doesn't leave fuzzies in the barrel, and is cheap. I swear by this swab. It's too good.
