To be clear....
If as a winner you're not sure how to test, or what to do, to test, it's easy.... Your entry is what you do. THAT'S WHY YOU WON.
So if you promised to swim 5 meters in pink custard, then you got to do it, and prove via photos (approx 4 should be enough, more is better tho).
I received item A, describe what it looked like n photo
Talk about specs if you wish
main event The test.... talk about what you're planning, what you're expecting to happen (photo of set up). Describe how it went (one reviewer took photos of themselves in the shower, proving waterproofness of the headphones)
result of test talk how it went, we're you surprised etc
This is JUST my idea to help the nubes
When you receive the email, it's purely a rough guide to testing n reviewing... not instructions.
