Counterfeit SD cards at Wish and Geek
Do not purchase memory cards from Wish or their alternate app Geek.
The other review is correct I believe in that there are many sellers that peddle their product through Wish.Anyway, the memory cards sold are fake.
For some, the prices alone should alert you. I think the current price for a real 128 GB class 10 card is close to $1000, but Wish is selling them for around $10. No matter the size, most of the memory cards are only 7-8 GB of actual memory but have been hacked to read as larger. To a computer/phone/other device they will appear to be the advertised size.
Once you fill the actual memory, anything else you try to write to the card is lost. You may see the file names listed, but an error saying the files are lost or corrupt will come up if you try to access them. When you ask for a refund you are told to mail the fake memory back. They know that for most of the items they sell the return shipping to China is prohibitive.
In my experience, they will also give you the run-around and then tell you that it is past the allowed time for returns.
Once the time ran out they wouldn't respond to any direct questions, they would just send back the same form letter email saying that it was passed for a refund and there was nothing they could do.
If you have bought flash memory from Wish (or anywhere for that matter), download and run a program called H2TestW.H2TestW will show you the real size and read/write speeds of your flash memory.
Reviewer is in unhappy mood. This person is quite happy with cheap stuff and stated that there is a room for improvement of fake stuff and taking my money. Please immediately contact the author of this review to discuss pricing issue of memory card. Wish needs to read this review and look into the issue (if any) according to poster's claims.
