Review on CO2 Inflator Kit For Bike Tires - 5 X 16G CO2 Cartridges, Presta & Schrader Valve Compatible, Insulated Sleeve Included by Dominic Kimbro

Bought a couple of 20" fat tire ebikes a few months ago and promptly tried to educate myself on how to prevent flats.That said, if a flat should happen, it looks like it would take a lot of effort to hand-pump the tire back up. So then I tried to educate myself on CO2 inflators.This product is the obvious winner. It is machined beautifully out of solid aluminum, not plastic, it screws onto the valve, and they even include spare o-rings (under a screw) so the thing can be used forever. It's extremely compact and they throw in some cartridges and an insulating sleeve.Perfect product for the job and at a low price. Of course, hope I rarely need to use it, but it will make changing a flat that much easier.
