Bullet proof; works every time; fills both presta and schrader valves; inexpensive cartridges; uses threadless cartidges; locks on to valve before trigger can be used; safely discharges any remaining air before allowing unit to be unscrewed; pumps up tires in seconds. Effortless inflation. Easily inflates road tires to 110 lbs if not higher.

None I have found thus far, but always have a hand pump on your bike just in case.

Very good product quality; reasonable price; cartridges available every where.
