I can tell it's what I reiceved ... or It's better to return it with wrong item received ?

Either of the two will work, or you can use the sealed box method by replacing the original Item with anything of equal weight.

Thank you @mothered, I will see for the sealed box (I'm sure you post an article about it in you blog) 

Thank you !! 

You're welcome.

Yes, I have written a guide for the sealed box method. You can locate It In the "Social Engineers Directory", or simply use the search function.
