After manually inflating a newly acquired SUP a couple of times it become obvious that a technologically more advanced tool was really needed, and feel quite happy about getting this one.
Works without any issues for already the second season, pumps up to 15 psi (I have no need for more) fast enough to not bother exactly what time it takes, also very useful for my mid-sized inflatable boat (needs 3.5, 5 and 8.5 PSI). Deflation function is also very handy for storing SUP or boat back in bags from which they were taken out.
Very satisfied that went for battery powered model (had some doubts about this) - the pump is much more practical to use without worrying about its distance and connection to your car. There is an ample reserve of power for inflating-deflating the SUP or the boat for a couple of times, and the capacity for 3 SUPs that they state seems very believable.
The torch function is more like a gimmick - it switches on by default and then you need to find out which button to press to get rid of it, but I reckon some people could find it useful.
The noise apparently matches the device's inherent functionality, don't see any issues with it for outdoor use. If it feels like the pressure is not going up fast enough, check the hose's connection to the pump and screw it more tightly (it could easily unscrew whilst trying to properly connect the other end).
