Received this promptly. Easy packaging. pretty straightfwd. I like that I switching between valve types isnt a headache and simply fixed screw and unscrew the valve without removing completely . While anything this size and portable will involve some sort of a work out while using to get to 120 psi it took me about 2-3 mins from flat to full. It does heat up a little but expected i guess given it is stainless steel which will hopefully prove longevity. There is a gauge on it which is very usefull and in thread with the tubing and hence not a bulky add on. has a release valve too. all in all a good buy.
