I prefer both USA made mods and Poland made mods, especially when the latter ones are made by me
It makes no difference for me whether the components for my mod (i.e. tube) were made in China. The majority of the stuff worldwide is made in China.
Sidewinder is a simple mod, just like GLV. It holds no PCB inside. I think that swap of the Sidewinder's button for a more solid one, maybe swapping the cables inside, and adding the Kick (or other similar device) it could be a nice VW mod
It's only serious disadvantage relating to GLV would be the weight. GLV is made of alloy instead of the copper (as in Sidewinder) and this makes it lighter.
Couriously, Chinese can also invent they own products that are inovatory and doesn't resemble anything else - Joytech's eVic for instance.
