Review on Effortlessly Inflate Your Bike Tires With BriskMore CO2 Inflator And 12PCS X 16G CO2 Cartridges - Suitable For Presta And Schrader Valve, Ideal For All Mountain And Road Bicycles by Bruce Cavett

I'm always hesitant to buy 'no name' products on Best Buy but the positive reviews for this seemed to be written by actual cyclists rather than just generic product reviewers. And it turned out to be true, this 'Briskmore' brand CO2 inflator works great, a fact I got to test when a friend flatted on a ride just a couple weeks after receiving the unit.As others have noted this inflator has two key advantages: 1) a control valve that precisely controls flow and inflation rate into the tire, and 2) direct screw-on to Presta valve to ensure no CO2 is lost or wasted in the process.Until now my favorite CO2 inflator has been the Lezyne Control Drive that features a control valve but uses a standard press-on Presta adapter. And my favorite floor pump has been Lezyne's Floor Drive with screw-on Presta head for secure valve connections. Briskmore combines those two key features in a single portable CO2 inflator. Brilliant! Why didn't Lezyne do this?
