It is quicker thatn 6 - 10 seconds when I have only 2 hooked up. If put all three on it is even slower.

I don't have a pump other than a air compressor at this time. I did hooked up all the hardware with just one retract and it is stil slow to me compared to others I have seen here. I can turn the board upside down and it will sometimes pull the wheels up all the way, but rarely.
