It maybe small but it is accurate and very very well made. You can slip it in your backpack with your multi tool and forget about it - until you need it. Either out on the trail or at home in the garage, in a flash it folds out and with a good stroke length it takes no time at all to adjust to your desired pressure accurately enough for any enthusiast. I've had mine for the best part of a year and despite rattling around in my backpack its tough construction is unscathed, all the fixings are in perfect condition even after a couple of ham-fisted trail side adjustments with cold and wet winter fingers. It may not be the cheapest but I won't be purchasing a plastic pump again. The only shock pump you need.
