You have the enter the tracking numbers yourself, no way to have the system scan you gmail or yahoo account to do it for you. After you enter the numbers on the extension, they do indeed show up, but no status. You have to click on each tracking number which brings you to their website to get the status of the shipment. If you asked me to think of a more useless chrome extension, I would not be able to do so.....completely and uterly pointless and the others on here who have left more stars are just being way way to generous in tehir review.

It is convenient to check the parcel delivery status just by clicking the extension icon on the browser, and love it can remember the checking history now!

It would be much more functional if it had data integration with the apps they forward you to download. Also just clicking on the extension only opens up adding a tracking number. User interface can be better. In order to open the package list you must add a package. Seems like a minimalistic extension separate from their apps they provide for android and iOS.
