Review on 🚲 Bike Pump: Portable High Pressure 130 PSI - Tire & Ball Inflator with Repair Kit by Ryan Lawson

I bought these to have a pump for my bike tires that use standard Presta valves. Simply put, this pump will not block or seal Presta valves. It doesn't inflate tires and when I tried to jam the pump on the presta valve with any tire pressure it opened the valve and deflated my tires as it didn't form a seal. In my case I now have a bike tire with no pressure and no pump to use. I know you're thinking it might have been user error, but I used a similar but less expensive pump on my tires. a few weeks ago and was able to inflate it with no problems so I'm sure my problems are related to this cheap product.
