I have had this pump for almost a year and love it. I used it for my road bikes, mountain bikes, and downhill bikes. The gauge seems much more accurate compared to my Joe blow pump I had before. Also the presta speed chuck is genius, no more breaking valve stems from time to time. I also like the screw on schrader side for my downhill bike. Easy to use and accurate when filling up, I need consistency when filling the tubes on my race bike.
