I've purchased a few items through AliExpress but had a bad experience with the purchase of a laser pointer. It was non-functional straight out from the container and I made a short video showing it didn't work by showing a functioning light, taking the battery out, and using the battery in the laser pointer and it didn't turn on regardless of what I did. Despite showing it was obviously faulty, they chose to disregard that and deny me a refund. Therefore, the phrase "caveat emptor", or "buyer beware", is very appropriate for AliExpress and its associated vendors. Don't spend any substantial amount of money on any of their products because you may receive junk or cardboard pieces that are nothing short of fraudulent practices and lose your money to someone that doesn't deserve it.
