CO2 Inflator Kit with 16g/ 25g CO2 Cartridges - Presta & Schrader Valve Compatible - CO2 Bike Pump for Road and Mountain Bikes

I've used this thing to get my nephew off the side of the road when his spare was flat. Put one in my bike and all other vehicles I drive alot. Buy it.

This inflator works great. I have used it to fill bicycle and motorcycle tires. It probably works well with car tires as well but I haven't tried it with those.

Edit: After working with the seller we were able to understand that we probably received a defective by fluke. They sent another one and we have had no issues. The seller was prompt and even wanted to investigate the failure so they could continue to improve their product.Original post: I bought one and loved it. So I got a second one for my wife. The rubber O-ring ripped the first time she tried to use it. She had to waste 2 CO2 cartridges just to finish the race she was in.

The wheel/tire set I used this on was a DT Swiss R460db 700c rim with a Vittoria Zaffiro Pro Slick 25c tire and TPU inner tube. When I used this inflation system, I was indoors with an air temp of 60 degrees F. I screwed the cartridge into place at the bottom of the nozzle. No problem. As with anything presta nozzle, the one on this system pressed pretty easily into place over the valve. When I turned the activation lever, the nozzle very briefly leaked a bit of air but almost immediately sealed into place. The tire requires inflation between 100 and 130 PSI. The system filled my tire to just over 100 psi with a more to spare (though I doubt it would be near enough for a second tire). When the CO2 expanded from the cartridge into the presta valve, I got the expected thin icy layer over the cartridge (thanks for the sleeve!) and at the connection between the valve and the nozzle. The rubberized material in the nozzle contracted and gripped the valve to the point I couldn't pull it off. But the and of the nozzle is made to turn freely, which allowed me to essentially "unscrew" the nozzle from the valve with zero loss of air. I used this to inflate my tire in my living room before needing it for the first time on the road. Based off that, I'm confident that it will work great if I need to change out a tube on the road.

Why did you pick this product vs others?:No particular reason. Used it today, first flat in 30 years. Works great.

It sucks that amazon give you a returning window open on an item that you can't possibly test unless you need it. When I received the item I tested it with a canister and work. After 4 months I did not have the need to use it so I kept it in my bike and secured in my bag. One day I had 2 flats on gravel and when I tried to use it, I realized this crap was empty. Thinking that just open by mistake, when I hit home after having to knock on someone's home to borrow a pump, I put a new canister and noticed all the CO coming out of the nozzle. Bad product quality. Cheaper is expensive, so instead of buying this rather buy a good one even if it's a Lil more expensive.

Very impressed with this product. Fit and finish excellent, packaging the same.

Just got them yesterday, but ice had them before and they worked good for a 4 wheeler tire, I got the 25s this time I had the 16s the last time, more co2
