Certainly their mini chainsaw is impressive on paper and would be fun to play with for a bit but I am always skeptical of the modern no-name gadgets that can do everything at a low price and have great claims on weight or accuracy. Not necessarily a bad product for the price but just leave the gimmicks and marketing out and just say hey it's cheap it works relatively well and have a great day.
Though the idea of being able to refill one of those AirZounds on the fly is an interesting idea. I never replaced my old one after the hose got abraded by the tire but for the time I had it, it was good to have and wish I had the ability to keep it inflated.
You can contact Andrew (in Canada), the inventor of Airzound, and he should mail a hose for your Airzound at a reasonable price. He is an approachable nice guy.
FYI, one refill of Airzound lasts for 25-30 blasts or 60-70 miles of riding for me. Usually, if I fill it once in the morning, I do not have to refill it before getting home at night. However, I would like to use the Airzound more on the road and assert myself against car drivers, so having the ability to inflate it more quickly in the winter is nice to have.
With respect to Fantikk, I did not calibrate its digital guage with any other device, but after using it for almost a year between bikes, the Airzound, and my car, I feel that its digital gauge is pretty accurate or close to being accurate.
