I love this little thing it works perfectly it's very lightweight and the build quality is very well made and durable. The inflator may pose a safety risk if used improperly!

This nifty inflator is small, lightweight and well-machined. I have used it with ease. The neoprene collar is great to place over the cartridge to keep my hands from getting frost from the cartridge. The dial valve allows me to gradually let the tire inflate. I have to make sure that I screw the inflator all the way onto the stem but not overtighten. The neck of the device swivels so you may think that it's born in place but it is. Make sure to hold the inflator straight in line with the valve…

This is a great little valve for using with CO2 cartridges for filling MTB tires. Works well, doesn't leak air and closes off well when you don't use the full cartridge, with minimal gas leakage.

Great little portable air compressor when a C02 cartridge is screwed into it. Bit of trial an error when your only adding five two ten pounds of air. Didn't want to over inflate tire so 7 pounds of air took about ten minutes. I kept sticking the tire gauge on it to see were I was at. After a few times of adding air you get a pretty good idea of how long it takes.This is a solid and well made inflator. The Cartridge screws in till it's snug and your ready to go.

I like this style because it’s reliable and doesn’t freeze up like some of the press to release ones. Since i can valve it off, I sometimes get a second shot.

I tried it at home first just to make sure it worked, a week later I needed it on the trail when I blew my rear tire off the rim on a hard 90 degree right hander. The tube came out between the rim and the tire (4 inch fat tire, lo air pressure) but it didn't burst the tube, had to air it down to stuff the tube back in, used one 25 gram Co-2 to inflate back to 9 psi and in a few minutes I was back to having fun. Takes up almost no room, and you can regulate the gas flow making it very useful on…

My only issues are:The instructions were very badly drawn (there are no words, just arrows and drawings). I had to look up YouTube videos to figure out how to use it.It’s hard to unscrew from the tire after the co2 makes the screw part really cold.

The product is as described, looks well made and looks simple to use (hence the 5 star on ease of use). Fortunately I have not had a flat tire since the purchase and hope not to. But again it is solid metal, fits in the palm of your hand and should work well with the CO2 inflator cartridge

I'm about to embark on a long motorcycle trip so purchased this and some CO2 cartridges. I let some air out of my front tire and used a couple cartridges to test it in the garage today. It actually worked fantastic and I'm glad I bought it. I struggled a bit getting my first cartridge to work. I did screw it on tight enough to puncture the cartridge but then when I tried to inflate the tire it more or less did nothing. It was as though the cartridge just didnt have enough pressure in it to…
