Review on 2-in-1 Dual Single Head Valve Core Remover & Tire Repair Tool Set by uxcell by Wayne Girard

One of the reviewers said to shell out the rest and get the screwdriver version. I agree. I bought it to use on a large Schrader valve for a 2007 F150 and it worked. It took some effort and didn't work properly, but after some effort I unscrewed the valve and installed a new one. The reason you don't need a reversible tool is that you have to press on the valve to compress it. Spring to open the valve. +1 for the available option. The quality of the instruments is not bad, but not perfect.
