None that I can think of AT ALL!
At first, I had a Max-Flo Inline 4500 on my gun, but immediately I didn't like how heavy it was. It balanced out the gun nicely by moving more of the weight towards the center of the length, but I just wasn't comfortable with it. On top of that, with its floating poppet design, it was very picky when it came to getting dirty and the least little bit of anything would cause a leak. Even though I got it repaired by Smart Parts for free, I still moved to the Micro Max-Flo and haven't looked back!
This thing is amazing... small, light, reliable, and everything you could ask for in a quality piece of equipment. Being preset at 800 psi is fine too... who needs a LP bottle reg when there's a secondary reg in the setup? Not me...
Pair this up with a 68/4500 and you have an excellent air system worthy of some of the best names in paintball.
