Aihomi CO2 INFLATOR - Simple & Safe Inflator Tool with Cartridge Storage Canister – Fits Presta and Schrader Valve – CO2 Bike Pump for Road, Mountain, and BMX Bikes - No CO2 16g Cartridges Included

I only give this two stars instead of one because it can inflate a tire. There are two main issues I had with this inflator. First, the cap on the bottom that threads into the cylinder that holds the CO cartridge and drives it up into the puncturing pin is incredibly hard to twist tight enough to puncture by hand. There is no grip on the cap and it is to small to grasp and turn with enough torque to puncture the cartridge. I had to use vice grips to twist the cap. Secondly, once the cartridge is seated and punctured it does not keep a seal. The cartridge is completely empty within a couple hours. The seal wouldn't be such a big issue by itself since you would think, "just don't puncture it until you need to use it". That would be fine if I could twist the cap on tight enough with my hand but because I can't, and I am not weak, I have to carry a heavy pair of vice grips in my bike bag in order to use this inferior tire inflator.

The description is wrong, it states that it accepts threaded cartridges, it does not. If you look at the picture you'll clearly see that it can't accept threaded cartridges. It's made from a cheap flimsy material. This is cheap even for a Chinese knock off! If you buy it, you'll be returning it, save yourself the trouble and just don't buy it.

I bought this to euthanize rodents that I raise for snake food. It says to use 16g co2 cartridges but since I had a bunch of 12g cartridges (for air gun) I was able to put 2 pennies in the bottom of the cylinder and it worked well. It is hard to pierce the cartridge. You really have to twist HARD to make gas finally come out, but hey for the price, I’m happy.

I bought this to use as a way to inflate tires around the house... wheel Barrow, ATV tires on trails and lawnmower tires. Works great with a 16g cartridge. Because it can take threaded or non threaded and if you don't have a 16g cartridge, you can use a 12g (that are sold everywhere) in a pinch as long as you have a nickel. I do not endorse or advise anyone to not use the correct equipment that this device was intended to use. I am super happy with this product and will recommend it to others.

This is very excellent Co2 inflator. It is safe, small and comfortable to use. One of my friends introduces the inflator for me and I bought it. I believe that nothing compares with the CO2 Inflator by AIHOMI. It is extremely functional! I am very impressed with the level of quality! It allows you to store your CO2 cartridge in the base without screwing it in and breaking the seal on the CO2 cartridge. You will never be dissapointed with this inflator. Absolutely, I will buy it again for some of my friends as gifts.

There are NO cow cartridges included. I must have misread the description. Should include at least one.

I like the fact that both types of 16 gram C02 capsules/cartridges fit in this Inflator. With the proper little spacer one could use 12 gram C02 caps/carts. Although they will not fill a large tire like 26" but you can use to start or top off. It takes all of a 16 to fill a 26" x 2" 35-40 lbs depending on outside temperature!

Ordered this for my dad for his birthday because he loves to ride his mountain bikes any free time he gets. This inflator is the perfect size for him to take on day trips in case of an emergency. The inflator is about the size of my cell phone and can fit in someone's pocket without a problem. I know he is going to love this and can't wait to give it to him!
