Seems perfectly fine, could have come with a foam sleeve to push it to five stars.

I am paralyzed and every now and then I want to or need to get into my chair for a while and then I go to get in it and the tires are flat when I’m in my chair trying to pump up one of these skinny tires, I it’s just like a tire on a road bike, it’s nearly impossible to use a hand pump and get it up to 80 pounds. I bought a small form factor tire inflator. They took one of these cartridges in less than two minutes. I filled both of my tires up. Now I carry it with me all the time , I used to do criteriums, which is basically a square or round loop 1 mile per lap and you weigh push for 20 miles as fast as hard as you can go and you’re in a very tight peloton group, it’s brutal! I would love this back then I had glue up tires and every now and then I will get to the race and one of my tires will be flat. I kept a folded up one with glue underneath my seat, so I went to stick it on my rim and pulled out my quick inflation device it put 90 pounds in that tire in the blink of an eye and I was ready to go in under five minutes. The cartridges hold exactly the amount of air. I need to top off two tires. If I have a tire that’s completely flat it will bring it up to full pressure with a little bit left over for the back side or the other side if you’re in a wheelchair , great product I give it five stars.Joey
