Is it safe to buy baby product from shopee or taobao to save cost?

I bought most of the stuff from shopee but usually from official store. As for Taobao, I bought clothes and some toys (which I used it to do busyboard), but I will read the review before getting them. Just make sure to wash them and disinfectant or sanitise them properly before giving it to your baby, as they tend to put things in their mouth.
