Before I was into cycling, I purchased the Nitecore BR25 bike light and Drift Ghost X bike camera from Aliexpress through the respective official brand stores.
That was something like four years ago, and I'm still using those items today (on my bike).
I did buy disk brake pads from Ali for my e-scooter, which I'd probably do again if I get a bike with disk brakes.
Other stuff I own that could be purchased from Aliexpress include several Rockbros items.
