That sucks.

The general rule of thumb is if it looks to good to be true it generally is. There are market derived limits for goods so although some cost can be offset buy bulk buying if a product is very cheap it generally means that it is of very poor quality due to the use of sub standard components or it is part of a scam.

Thank you very much for making people aware of this. You should also contact Aliexpress, we are sure they will also not be very happy about this as they are trying very hard to improve their reputation as a secure buying environment. We couldn't say you will get your money back but they should investigate the company.
