My grades and intellectual confidence have improved thanks to them.

Zero star. Worst company to deal with. Especially "Etrade Technology Co. Ltd".

They send you broken junk product.
Waste of money.
Waste of time.
No replacement.
No refund.
Online review is all lie, don't ever trust them.

No one to call but just online chatting and waste of many hours chatting with no outcome. Online conversation keep disconnected and very frustrated changing person and asked you to repeat again and again and pushing you around the brush. Video cannot be uploaded to their website even with proof. Asking them to provide their email address, they refused thus intentionally delay till the time over and not helping at all. Such a big company but no one can provide an email address and let their IT technician to upload the video. Video can be send to seller with email address but cannot upload to the website, what a joke.
