Manual Transport CO2 Bike Tire Inflator, CO2 Inflator, Fits Presta and Schrader Bike Valve - CO2 Tire Inflator for Road and MTB Pump Accessory - Includes Insulated Sleeve - No CO2 Cartridges Included

Great price and outstanding performance! I have owned it for less than a week and used it twice - worked perfectly! The instructions warn you to not have a CO2 cartridge attached longer than 24 hours - my second usage was with the same cartridge 23 hours after the first use - it had retained pressure and was flawless in delivering the second set of pressure improvements.It is much smaller than you may believe - I know I thought it'd be more massive.

This is an excellent CO2 inflator! I purchased it for minimalist under-saddle repair pouch and have used far more times than I care to admit. Simple on/off valve with clearly marked stages. Liked it so much I bought another one for garage use. Great value.

Wow, the ability to almost instantly inflate a fixed flat tire while in the middle of nowhere is awesome. Inflation is done with compressed carbon dioxide, which is not appropriate for long-time use. So get back home immediately or to where you can replace the CO2 with pumped air. This unit is machine molded metal, so my only concern is durability, but so far so good.

I liked the fact that this has a very simple valve to open and close. It's a good idea to have extra Co2 cylinders on-hand as well. Very handy when you have a blowout on the road. I always carry a spare innertube and this inflator in my toolkit.

Great item and good quality the valve is easy to turn and the sleeve is a great idea

Product came quickly, I have used it once and worked great. It is really nice to have a nice on-off lever to easily control the flow of CO2 into the tire. Lots don't offer this

Very good item

This thing is compact! I don’t have much space in my pack so I was glad this thing is smaller than I expected, as you can see in my photos (co2 canister not included). I have yet to actually use it to fill a tire, (hopefully I don’t ever need to) but it seems well made so I feel confident it will do the job. I like that it will do shraeder and presto valves without the need for an adapter.
