I like it and I would recommend it.
I like Fantikk so much that I am now looking to screw on a quick connect/plug-in chuck to the threaded connection so I can inflate the Airzound quickly while riding, especially since it is winter. My situation is the exact opposite of yours.
How do you know this Fanntikk has a 1psi margin of error? Was it marketing or have you actually verified this with a calibrated system? Certainly their website doesn't give confidence of that kind of accuracy in any verifiable situation. It looks like a serviceable multi purpose thing that can inflate tires as well. 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.
