[Hypersomnia]

Oh alright I completely get it,

When I talked about sealed it's because you said " the package was sealed of course" and I was like: But how can he knows if the mouse is inside without open it xD
Everything is clear now,

Alright I'm going to try it today and see how it goes, once you received the package you contacted them or you waited for it a bit?
Any preference regarding the delivery option?
Plus, I'm not at home the entire day, is that a problem?

It's fine if you wait a bit, but i recommend doing it the same day, just to let them understand that you really care about the issue, adds more credibility i guess.
Delivery it's on you, if it's free shipping just use the standard one, if you got prime then even better for you.
Keep me up to date dude, i really wanna know how it goes
