U.S. buyers of the Huawei Mate 9 can score a free box of premium accessories13
To receive the gift box, click on the sourcelink and complete a quick survey. There are no embarrassing questions. Huawei simply wants to know things like the phones you considered buying before choosing the Mate 9, who did you buy the Mate 9 for, and how frequently you buy a new smartphone. You will need the unit's unique IMEI1 number found in the "About phone" section under Settings.
Unless you have Amazon Prime, you will have to pay for shipping. Taking that expense into account, you probably will still come out ahead. We don't know how long this offer is available for, so if you'd like to receive this gift box for your Mate 9, get started on answering the survey now. It should take you less than 10 minutes to complete.
