We offer a 5 year global warranty, and have a 0.005% returns rate on our products, so the quality is very high. The ball head comes off, and all threads are universal 3/8"-16 or 1/4"-20, so there are no weird thread sizes that require specific adapters. I suspect the AirHed Neo is stronger than your Gitzo head (dependent on which Gitzo head you have), so you might be surprised :) . Also worth noting that we're the only brand that offers fully detachable feet and a multitude of footwear options for different terrains and surfaces at this price point. And, if you're interested, we currently have an Instagram project running called "From Concept to Corey" ( #ConceptToCorey ) where we are showing the design and build process, and detailing what it takes to bring a product to market. Hope that's helpful.
