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

Works flawlessly. No co2 wasted at all. Easy to use. Screws straight onto the presto valve before or after connecting your cartridge. Seems to be built with good quality, and comes with spare o-rings stored inside if you happen to be missing one one the trail. It’s super small and fits in any bag making it super portable. I highly recommend this item I’ve used it to help fellow riders multiple times already and it’s still in perfect shape. Unlike a lot of the other brands where you use them a couple times then they are trash or forget how to use them after going long periods without this one is the perfect fit for any cyclist.

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!

In the instructions, I discovered that this fine company includes 3 spare gaskets in the case that you blow one. That's a very nice thing they do so that you don't have to replace the entire inflator device. As it turns out, I blew a gasket (no fault of the company) when I got back to the house after my ride. Out on the road, the device worked great. I fixed the flat and I was able to complete my ride. When I got back to the house, I failed to let the pressure out of the canister slowly by using the release value. I just unscrewed the CO2 canister and BANG!!! It scared me to death AND the gasket that was inside swelled and blew apart. The discovery of the extra gaskets made my day. It's nice to see when a company can foresee what may happen and provide a solution, without having to buy an entirely new product.

I should have researched the cartridge capacity before ordering. The container indicates that 16 gram cartridge will fill my 700 x 38 tires to 58 PSI which is just enough. I should have ordered the 20 gram. Definitely need the larger size for mountain bikes.

Make sure you've got these before you head out. They're easy to use and don't take a lot of space. There's just enough air to fill a road bike tube without blowing it. Highly recommended.

Small size fits in my pocket with no issues

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.

Great alternative for flats while biking! I carry a spare tube and this item. I ride 14 to 20 miles and should I have a flat away from the home I have the ability to repair on the spot.

My husband bought these as he recently had a puncture out on a bike ride, and a friend fortunately had one of these to hand. Sorted the job out. Compact to store en route and effective in puncture emergencies.

Einwandfrei! Erfüllt seinen Zweck und läuft zuverlässig

This is so simple to use. I tried it on a couple of tyres to get the hang of it. Mini cylinders screw in easy and remove easily when used. The tyre pumped up in seconds. The valve is really good and sensitive to how much you open it. A great buy.

Kam letztens zum ersten Mal nach einem Platten zum Einsatz. Funktioniert wahnsinnig gut!

Which is good. Good quality and only for emergencies.
