Review on 🔧 Mini Bike Pump with CO2 Inflator - Dual Mode Hand Pump & CO2 Valve - Portable Tire Pump with Patented Auto-Switching Twin Head Fit Presta/Schrader - (Cartridges Not Included) by Mike Swanson

I love the idea behind this pump and the mount is very nice and efficient. Once installed it looks great and is very minimal. The fact that it can use C02 and regular air is great. The problem I have is that with any type of valve, you really have to screw the pump onto the valve for the air to flow properly. This means I had to turn the device all the way clockwise 4-5 times to screw it down and keep it airtight. This is not possible when the tire/tube is mounted on the wheel. The spokes do not render this device useless. I thought maybe the blue/red heads would rotate or wrap, but they don't move. Most pumps just push and then latch with a lever, which definitely doesn't work. It's a shame because otherwise it would have been a great product in my opinion.
