Great practice would be doing a research on the reference link before placing an order. Always chat with the seller if you're uncertain about the quality.

Buy from B2C tmall if can. Their store & product ratings are much more detailed & quality is better.

Here's how I categorize the item quality (tmall rating):

if review <= 4.7 out of 5.0, don't expect the quality is better than what you can get in Malaysia.

4.8, Check the user reviews thoroughly, the item has some flaws but acceptable for many buyers.

4.9, Recommended. Usually, their price won't be the lowest but their quality/packaging definitely belongs to above average.

5.0, Product might be new or perfect.
