Review on Vibrelli Mini Bike Pump with Gauge - Presta & Schrader - High Pressure 110 PSI - Portable Bicycle Pump for Road, Mountain, BMX Bike Tires - Mounting Bracket Included by Darth Naubert

This vibrelli promises a lot (and works well enough) if you don't mount the pump on a bike frame. I mount pumps on a frame and this pump has a serious defect. The pump handle does not lock when not in use. This means that the handle (or body) can slide down and affect the ride. The best pumps have a swivel feature that locks the handle in place, ensuring the pump does not move freely and is held securely by the frame mount. The Vibrelli frame mount cancels out some of this movement, but the pump is not held securely enough, especially if you are traveling on a bumpy track or road that could cause the pump to slip into the frame mount. Deal breaker for me. I will toss the pump in the parts bin to wrap or give away.
