Well... if you play quick games where you absolutely need more than a hoppers worth of paint, this is great... I guess... Really, I got this for free from a friend... I don't use a lot of paint, even in huge matches, so this is more of a safety for me, just incase I run out. There are a ton of flaws with this setup, and I would much rather have a better setup, but with my 98c, I'm fine...
Conclusion:
Great if you don't use a lot of paint. A lot of room for improvement, but it works for me... this gets a 7 just because it gets the job done...
