Aleric CO2 Bike Tire Inflator, Quick & Easy, Bicycle Tire Pump for Road and Mountain with Insulated Sleeve, Fits Presta and Schrader Compatible, CO2 Bike Cartridges Not Included

The inflator was extremely difficult to apply to the stem of the inner tube and when the CO2 was released into the tube it didn’t have the pressure or volume to inflate the tube to a rideable level. Do not rely on this product for on the road repair.

I liked because is easy to use and small.

Pretty straight forward, screw it on the presta valve, screw on cartridge and unlock the unit. Co2 went everywhere but inside the tire, glad I was not out on a ride when I tested it out. Make sure you know how to use a presta valve first and open up the valve lol

The inflator is excellent quality and easy to use. I really like the insulated sleeve to place over the C)2 cartridge so your hands do not freeze.

Got a flat tire on mountain bike six miles from home.Did repair, and when it came time to use this device, the gas trickled out of it and didn't inflate the tube more than a few pounds.After waiting for gas to stop, I removed the cartridge.Passing biker lent me a pump to inflate tire enough to get home.Threw this thing out and ordered a traditional mini pump.

Finally! This was the 3rd model I tried. I was about to give up on CO2 or buy an expensive brand name inflator as a last ditch. This thing works like a charm. The on/off works flawlessly. Simple. I trust it isn’t going to leave me stranded. Look no further, this is the inflator you want.

Not sure if it was just faulty or just badly designed, but it didn't work with Presta valves. Glad I tested it before I had to use it on the trail. It wouldn't tighten down on the valve at all. Works fine on the Schrader.

I bought this as a high pressure option to assure my tires are at pressure when I don't have access to a floor pump. It will be good for my needs.
