Model was recommended to me as replacement by customer service rep because the flexible air hose is much gentler on presta valve stems than conventional compact frame pumps. - STILL very reliable either to top-off air pressure or repair flat on the road.
Brought this pump on a European cycle trip for topping up tire pressure. Never bothered to buy CO2 cartridges since it was light enough to carry for emergency flat repairs. Pressure gauge seemed accurate enough to avoid overunder inflation.
