I have bought a few phones from gear best and banggood but the problem is if you can update the software ,the last one I bought for the wife was a Sony xperia , when I tried to update it was a Japanese market phone model and I couldn't do it and nor would the Sony dealers because they hadn't sold it .It is still working but she only uses it as a phone and for facebook .I'm literally just about to buy a xiaomi mi 9t pro. Just wether I go with eBay or Gearbest to buy though...
