Buy pendrive in China worth? Generally no. The prices here in Brazil are very good and you can buy with the store guarantee, which is always a good idea. This below, the old Kingston DataTraveler, can be purchased in Rio de Janeiro at about 20 real, the 8 GB version.
Don't be fooled by the brand name Kingston, because it is possible to find products of questionable quality. This is very good, Although slow even compared to other non-branded.
Despite slow, the quality and finish are very good.
Certainly reliable device, in spite of taking too long to write files.
This Flash drive has an interesting design. When not in use the metallic piece hides the USB.
Below the photo of the pendrive ready for transport, with the protected USB.
I did a benchmark using the CristalDiskMark to find out the Flash drive performance. Playback is slow, about 16 m Bytes per second, Although acceptable. The recording is the weakness, next to 2 ~ 3 m bytes per second, that certainly will make you lose a lot of time to transfer files.
Good product considering the price, but I think you can spend a little more to get a faster device. Who want to buy it in China, Here I leave the link to the product. In Brazil, However, will come out more or less the same price, that without considering taxes.
