Now I ordered 130 items at AliEpress, and overall I'm pleased with the things I bought there.
But,... you must be careful. Some sellers are bogus. 8 orders of the 117 things I ordered didn't arrive or where faulty. So 8 times it went wrong, but I get partially my money back. I bought there a lot of different things, led-lamps, clothing, hearing aid, access/point-repeater, usb flash drives, batteries, underwear, shoes, SD-card, led-neon, led-dimmers, professional thermocouple, silicon baking mat, pool floating thermometer, hair clipper, leakage circuit breaker switch, sandals, passive POE injector, IR security IP Dome Camera, custom made neon, CAT 6 network cable... and much more. If you buy something there, you must communicate with the seller, otherwise it could go wrong.
A few things you better not buy on AliExpress are Smart phones or tablets. They are not build for the European/American market, so you will have issues regarding net compatibility.
