The pods weigh 4 grams, and the charging case at 38 grams. The missing Item method Is Ideal.

In that case, what is the threshold for "missing items" method to fail? I'd assume it varies from company to company, but generally I'm guessing anything under 1kg should work and anything over is more likely to fail?

For Instance, you cannot use the "missing Item" method on an Item that weighs 1kg, nor box the company by returning a monitor.

Also in response to this, I feel like this isn't entirely accurate. Missing item has worked for me on numerous occasions with the weight being completely off. You say that you cannot use the missing item method on something that weighs over 1kg. I'd say attempting this method for things over 1kg can be proved as a  false claim by the company, hence the refund cannot guarantee success. However, there are several companies who will not even verify the weight of the package and will refund simply out of good will. For example, I've done a £800 zalando partial (stuff I claimed was missing was about 15kg and the whole package weighed about 20kg). The refund was still successful and only took 2 days.

My post Is based on an Investigation opened with the carrier, whereby the consignment details are cross-checked with dispatch.

In this case, It "will" fail.
