As far as AliExpress is concerned they are useless, I received a faulty item form a seller, the seller refused to accept it was faulty despite pictures proving the opposite. Escalated the issue to AliExpress who have done NOTHING and trying to navigate their site to escalate further or get a response to the current escalation will either send you round and round in circles or just dead ends with broken links/missing pages.
Bottom line is you can get a good deal on their site providing you get a good trustworthy seller, which appear to be few and far between... so you are taking a big risk and be prepared to throw the money away, but you may get lucky and bag a bargain.
