What is that one piece of gear that you have that the name brand/original product is worth buying over the copycat or diy?
this is a great question to ask...
i use a lot of knock-off items because most of the time it really doesnt matter. like buying the great value walmart brand corn chips opposed to frito lay corn chips...whats the worst than can happen?
i dont take that approach with electronics or safety/recovery gear. although most things are made in china, there is still better quality control with name brand items (usually).
take a solar controller, for example... i use renogy and they are made in china...however, there is quality control because the solder joints are much better than they are on the cheaper knock-off versions. also, a lot of the wiring is better. a lot of the cheaper knock-off electrical tools are notorious for using cheap wire and poor insulation on motor windings, so that dewalt knock off drill that was $70 cheaper will probably fail rather quickly and definitely will not hold up to any constant use. same thing for cheap winches...their motor windings will probably use a copper clad aluminium wire with poor insulation that will not hold up for very long, especially in a rough environment.
name brand is also better concerning safety/recovery gear. one great example is a shackle. i did a lot of rigging offshore and we always used the Crosby brand shackles. purchasing got the bright idea to cut cost by buying shackles with CHINA stamped on them. we started having failures offshore and the cheap knock-off shackles were failing way before reaching their stamped SWL. after a few mishaps, any shackle stamped CHINA was banned from offshore use.
i do have some harbor freight shackles, but i dont use them for anything important
