Basically every single thing you buy in a store, is also available, at around 1/10 the price, at these sites.
The next time you need a kitchen gadget, tool, measuring cup, belt, socks, pencil. Anything. Buy it on aliexpress and save a ton, in exchange for very long shipping times, and you pretty much can't return anything (you can get refunds for defective stuff, but not for wrong size/color etc).
And it's not just a Chinese clone of the item, it's the exact same item, with a different name printed on it.
Every electronics I ever tried to buy cheap from China (e.g. from dhgate.com) has been broken. I have literally never seen an electronics that is remotely close to working from this source. I do believe that you can get something if you're lucky; but even after reading reviews and seeing good ones I got USBs that are not working (I tried to buy them out of curiosity, I just spent $10 or something).
