Reliability of the Chinese websites like alibaba amd aliexpress

<< < (3/7) > >>

EEEnthusiast:
I had ordered hundreds of parts from AliExpress but never had any issues so far. Few errors if any were due to the lack of English communication skills of the seller, rather than the intent. For e.g. in some cases the part colour may be different. Ebay is not that trustworthy in my opinion. I had been conned on ebay multiple times. Note that the sellers on AliExpress are registered businesses in China and not individuals. So that makes it more reliable.

They generally have more scams than eBay, e.g. several times I've ordered two or three units of an item and received only one. They make you jump through a few more hoops than eBay, but they tend to side with the buyer.

Taobao though, is a wretched hive of scum and villainy. For example, sellers routinely list STM32 blue pills with STM32F103C6T6 chips blacktopped and remarked as STM32F103C8T6s (and of course all the specs are of the C8T6). Taobao will refund you ... if you get an official stamped certificate declaring that they're counterfeit.

It's an unwelcome insight into the double standards that Chinese apply to each other.

I've had Aliexpress demand me a statement from the manufacturer that the parts are counterfeit. I've send clear and obvious evidence that they are, yet it has not been good enough for them. I no longer trust Aliexpress with refunds. They also often give just partial refunds even on stuff that is dead on arrival claiming it's some use to me.

I have bought many specialized / rare old industrial items from both over the last year - 10s $s to many 100s $s ea
I buy from 3! separate suppliers each time (for any 1! part I need), if it is a "rare" IC, I buy 5-10x each time. I make sure my service quote covers ALL the purchases.
My "running average" experience is -
ONE supplier will send a wrong part, completely or different enough, not to be useful.
ONE supplier will send a faulty part, or broken pins, or missing important connections
ONE will be late, sometimes very late
Rarely will all 3 orders be correct and on time. I NEVER bother complaining / giving only neutral or slightly positive feedback, NEVER lodge a dispute.
I have learned the system :-)
When I have a carload of "extra spares" built up, I'll just give them away, like I've always done. This system works fine :-)

I was a heavy ebay buyer, now eBay is my last place to go to.   Some seasoned sellers with high rating can game the eBay ssystem and play the system without loosing their money and their rating.  You can be sure that their communication of no-content  is immediate before the feedback window is over, and shall mislead you to go against eBay rule to resolve the dispute.  And when the window is over, they are gone, and if you trust eBay or PayPal, then you cannot be more wrong.  All the "money-back" promises when tested, are all broken.  You would think the communication messages can let ebay or PayPal side with you, you shall be wrong.  Ebay and PayPal are all BS, the Chinese aliexpress and taobao do that like a real businessman, they shall refund you and take the risk of getting back the money from the seller.  If both sides they think have their points, then they absorb the losses and trying to get seller to absorb some, and buyer to absorb some.  I rank aliexpress and taobao as good as Amazon for customer care.  Of course, pricing wise is a one sided thing.

I think it is very difficult for companies like AliExpress to understand if a chip is counterfeit or not. I think if you want genuine parts, buy from a distributor you trust. In the cases where it is obvious that the item you ordered and the item received are different - such as an item that does not match the original photo - AliExpress are pretty good at protecting you.

In your case concerning a board with half the flash memory, I can understand your frustration.
