I was looking at doing pulling a wrong item received with Amazon, for a new macbook pro 16 inch. The item weight is listed as 2.1kg, I was wondering if that is the precise weight of wrong item I need, or how much I can deviate by. What is a good item for this? I understand it's better to use an item from the same department (so an electronic that weighs around 2.1kg?)

Any other tips for the method? Thanks
