I have bought many items from many different sellers. (Mostly jewellry)

All you need to know is.
ALWAY CHECK SELLER FEEDBACK AND LENGHT OF TIME TRADING. (Anything above 95% is good)
ALWAYS READ TERMS OF SHIPPING. (You normally need to spend over 10$ for free shipping.)
ALWAYS KNOW HOW CUSTOMER PROTECTION WORKS.(this is most important.) You will be given a certain amount of days to receive your item. YOU must watch this as aliexpress gives no warning when it is going to run out. If you have not received your item b4 the timer runs out, the day before it ends ALWAYS OPEN A DISPUTE.
Until your item arrives and is in perfect condition. NEVER cancel a dispute until you have your item or your case has been delt with and you are happy with refund or replacement. NEVER cancel a dispute because the seller hounds you to do so.( And he will, always) then you get no replacement or refund.

Reason for this is, the seller never gets paid until you have informed aliexpress that u have received your item and it is as described and fit for purpose. Aliexpress holds your money until you tell them you have it or the customer protection runs out after which the seller automatically gets paid.

Out of maybe 50 sellers I have only been done 1 time. This was because I did not know how customer protection worked and let it run out b4 I got my item. Never received it either and got no response from seller.
I have found most sellers friendly and helpfull and a pleasure to deal with and for most part received excellent quality stuff for 1/3 of the price here.
It can be a great place to shop if you are armed with the knowledge of how to buy properly.
In general I would advise against electronic gadgets or very expensive purchases.
It's great if you are lookin for cheaper alternative knockoffs but ALWAYS do your research.
I have given you the know how now go enjoy shopping.
