The thing is, after using eBay - specifically ordering parts from Chinese sellers - I started using Aliexpress. The thing both sites lack is shipping option, as someone who lives in Europe postal services are key to receive the goods I ordered.
I started using Gearbest for two reasons: they only have goods that are original, no fake stuff. Xiaomi is my favorite brand, so upon realizing that Gearbest ships with DPD too, I ordered one. 120 dollars well spent, the thing is superb and original. That sums up both reasons: they don't sell counterfeit goods, like the 9000mAh 18650 batteries you can find on Aliexpress or on eBay.
Only legit stuff with a whole bunch of shipping options suited for your needs. So I definitely recommend, so far I ordered around 40 things from 3D printer parts to flashlights and electric scooter, and everything was delivered within the stated time-frame.
