I haven't actually used my airmoto yet, but I like the compact size and what I expect of it. I am a 71 year old widow. I learned to change and inflate tires many years ago, but I would have a lot more difficulty doing these tasks now. That makes the airmoto a welcome and useful item for me. However, I do wish they would price them more economically. I don't need multiples, just one at a reasonable price. I'm sure a lot of other seniors would agree with me.
