I was bummed when I bought the tiny toddler TMC version of the airframe. The quality level compared to the Lancer/TMC/Emerson FAST Bump options that are most commonly used in US airsoft, are a significant step up. The value for money is right in line with what you're spending. The shell plastic is thick and a bit heavier than those listed above. The pads are Team Wendy copies and much less dense foam. My Large Crye helmet cover fits perfect.
The rails are flimsy, and the fasteners mounting the nvg shroud are poor quality phillips. The NVG shroud itself is quite nice with an aluminum insert.
