Two things stand out, the fact that there's less than a mm of material around the fitting is, and is not concerning, as part of the overall design, the load is not centered on that tiny area, but spread over the entire area, but at the same time, being so close to the fitting, if a fracture started there, it would spread rapidly. Doubling the material (not necessarily expressed as doubling the thickness) would certainly help with the inevitable shock loads that would contribute to the failure. The strength of carbon parts is not necessarily measured in thickness. I learned this with landing gear on the drones. Impart loads in the direction(s) of the construction, and the stuff is darn near impossible to break. Do the same laterally to the construction and they break quite easily. The stuff is just fibres and resin after all.
The thing that is really interesting in the warranty is the commentary about UV. Carbon gets hotter in the sun than untreated aluminium. If there's no uv covering, how long will this stuff last?
