They work
Not much to say about CO2 cartridges. They either work or they don't. These work. They will fill your tires with enough gas to finish your ride.

BTD CO2 Cartridges, Great Price on a Must Have Item
These are standard issue threaded CO2s. Nothing fancy, but they work well with my Portland shiny metal object. BTD has them for a great price. Everyone should have a stock these for their rides and toolbox.

16g Threaded CO2 for my PDW shiny object inflator
I'm fortunate to say that I haven't had to purchase a whole lot of these. However, all it takes is one ride to remind you that you might ought to have a few extras on hand. I use the Portland Design Works Shiny Object inflator. These thread in securely and stay put. They also fit in my small under-saddle bag, which holds a spare tube, levers, inflator, tire boot, etc. I find that these will only inflate a 25c tire/tube to about 80-85 psi, which is adequate to get through the ride. If you happen to have a hand pump and get the tube partially inflated, then these are great at topping off to higher pressure. It all depends on what your tire/tube situation is and what you're willing to carry on a ride.
Tip: Cut a portion of an old tube and put it around the C02 cartridge. These things frost up immediately as they expend their compressed CO2. So, after mounting your tight tire back on the rim of your expensive carbon wheel, it can hurt when your tenderized flesh pulls loose from the ice-cold surface of the cartridge. An old tube will protect your skin and makes the cartridge just a bit less bulky in your saddle bag or jersey pocket.

Perfect size to carry a couple in my under seat bag.
I always carry a pair of CO2 inflators in my under seat bag. Normally I can only find 12 gram size. 20 gram cartridges are too tall to fit in & close my under seat bag. The larger 16 gram just make it. I carry 2 in each of my road & cycloross bicycles. So the six pack was perfect for re-outfitting for the season.

Reliable CO2 Cartridges.
These are reliable CO2 cartridges that last until you need them.
I've gotten cheaper ones before that turn out not to work when you
need them. These have always worked when I need them.

Exactly what I needed
I'm always a fan of threaded versus the container cartridges. Easier to transport. These are a great price and get the job done.

Amazing, just like a breath of fresh air.
My little saddle bag is too small to carry more than one cartridge and so I tape 2 extra one's to the seat post.

Quick refill
Anytime, anyone on our group rides gets a flat. I quickly change the tube. Having CO2 available to refill the tire expedites the process.

Always keep a couple in saddle bag. Generic name but same quality as more expensive name brand CO2 cartridges. No reason to pay more.
