Seem to be a decent price. Bought for use with my paintball gun to save bulkyness of my main Co2 tank. Work well after getting an adapter. I am not using for game play, as a bit small for that, but great for popping few shots off at the mice running around my garage. All in all, fit my needs well.

Works as intended. No corrosion present so far, but they're stored in a climate controlled area. I use these to quickly pump up my tires after fixing a puncture. Beware, when filling up, they get VERY cold. The canister will burn your skin upon releasing all the contents, so wear gloves and be careful when removing from the stem so as not to damage your newly installed tube!

We have used a different cartridge in the past and it hardly had an odor and it wasn't a problem to use. These cartridges, however, have a bad odor and can be quite overwhelming. Now I said all that to say that we are using these in a bit of an unconventional way. We are using these in a portable hand-held tire pump to spray when our dog is barking. It's an effective tool that dog trainers use to help deter unnecessary barking. Most people have experienced certain dogs that will bark at EVERYTHING and won't stop. Spraying this into the air is a startling sound to the dogs and is effective in curbing their excessive barking (for most dogs ;-) ). So with all that said, when this is sprayed inside a building, the smell is quite strong and often brings on a coughing fit. So buyer beware if you are buying this to use as a tool for training because it stinks! But if you are buying it for it's intended purposes then the product, as long as it's hooked up to the tire properly, should spray all that stinkiness into the tire and not out into the air.

I have been using the C02 for a long time, they are easy to use to fix a flat tire. Price is better on Amazon. I will definitely recommend for cyclists.

I have purchased two packs of Fast Rack 6 Pack Threaded Co2 Cartridges and they simply do their job. I use them on my 27.5 MTB tires that are 2.5" wide and it inflates them to 20PSI. No issues.

These are fatter than others and won't fit into a Digital Innovations AirDR CO2 duster that works with other CO2 cartridges (thinner ones).
