Raises cyclone feed rate
Clean looking
Works as advertised
Weaknesses:
Have to clean after each day of playing
Review:
This definitely does what it advertises. it vents the air much more efficiently than a QEV does and it allows the cyclone to cycle much faster. my rate of fire went from 19-24bps with this. The only thing is that you have to make sure it's well lubed and cleaned after each day of play. This is because of the openings in housing being slits instead of holes. I have been talking with the manufacturer and they are looking into possibly making them holes but I haven't had anything other than dust and a little grit get into my QEPH. Definitely a great product!
