Review on IDMAX Portable Bike Pump - Foldable Mini Hand Air Pump for Mountain & Road Bicycles, Compatible with Presta & Schrader Valve - High Pressure Tire Inflator by Jathan Louis

This was a good value pump so I can't expect too much. I wish there was a better gradient on the gauge as it's difficult to see pressures other than the nearest 5 pounds. The outlines are accurate to two pounds, but they are so tiny that the tip of the needle covers about 5 pounds. The hose is stiff and inflexible and the yoke doesn't seem to close my Presta valves. It drips and sizzles a lot. It takes a lot of strength to suck in more air than blow it out. Worked well with Schrader valves.
