Anyone bought anything off aliexpress?

All sorts of cheap stuff on there.. but???

I've bought one thing - a heated bed for a 3D printer - and it was delivered within a reasonable time. I understand your concerns though - I wasn't 100% confident until the package arrived.

Basically it's a Chinese ebay, without the usual buyer protections...

yes.. only for cheap stuff that is not a problem if it never arrives..

I've done about 10 orders, all but one has been fine.

The one that's wasn't okay was a pair of cruise control stalks for my vw, on one of the stalks a rocker switch had been pushed too hard and been pushed back inside the housing. Contacted the seller and he said he would send another. After a while the buyer protection was running out so I asked for a refund if he hadn't sent one out, promptly received a refund
