Review on GIYO Mini Bike Pump with Pressure Gauge & Repair Kit - Portable Compact Bicycle Pump for Road, Mountain & BMX Cycling - Presta & Schrader Compatible - 120 PSI by Erik Snyder

I am very happy with this pump. I tested the sensor for the hand pump and then the floor pump and it was accurate. The fastening system is perfect, nothing rattles. My only issue with this pump is all the extra parts they supply. I love that they have a repair kit but wish they had some kind of velcro pocket that I can attach to the frame rather than a small zippered back that just slides around in my backpack. I really wish I could leave my backpack at home and just grab my bike, pump and repair kit, but I'm not going to bounce it around in my bag while I ride. But that's the only complaint, everything else is perfect.
