CO2 Inflator Kits with 9X16g or 5 X 16g CO2 Cartridges, Presta and Schrader Valve Compatible, Bike Tire CO2 Pump, Included Insulated Sleeve

Worked perfectly and was very easy to use.

I had never carried a pump or inflator...and as you'd guess, that eventually proved to be a bad decision when flatting out about 15 miles into a metric century ride.I bought this to put into my new flat kit, and I'm choosing to carry two CO2 cartridges along with the inflator valve. Seems to be a good compromise of weight to functionality, and I figure if I ever need more than two CO2 cartridges I'm probably calling for a ride home.Good value and seems to be good quality. I hope I never have to use it, but it'll be ready when/if I do!

Comes with picture instructions but isn’t hard to figure out. Everything worked great, seems durable and fits on my presta valves. Would recommend/buy again.

Bought this to replace a cheap and leaky filler. This is much more sturdy and allows you to fill a tire without fear of leaking CO2 onto your hands. Wish it had a better storage container, but I've been happy with it's performance so far.

What a great alternative to a hand pump when you have to replace a high pressure bicycle tire tube on the road! It's small, convenient and easy to take along. Just be careful to open that valve slowly the first time you use one of these to make sure you don't overfill I especially if you're riding on thin tires.

It works as it should!

I love when things actually work as intended and pleased to advise this product is PERFECT. Easy to use and sves me from the hassle of using the large pump

Got a new ebike and needed something to refill the tubes if I ever got a flat. Didn't want a hand pump or anything battery powered, so I thought I'd get these. Fortunately, I haven't had to use it yet, but looking at it, it looks simple enough. Screw a bottle on, put the insulator over the bottle as it'll get cold when in use, then open the valve and fill the tube.
