I carry this on most of my tours and have had occasion to use it. It doesn’t have a pressure gage so it requires a guess and feel approach. I found that to be more annoying than I thought it’d be. I also found it takes a lot of pumps to get any air pressure whatsoever into your shock. I really wish it put out more volume per stroke. 3 stars for those downsides. It is very light and kind of a no-brainer to carry when you have two air shocks on the bike, but I consider it more for emergency use than trying to tune pressure.

I’m thinking about the new DXG version at 100 grams heavier but a gage and hopefully better functionality.
