I hate this.
Next day delivery takes at least two days and a weekend.
The mouse (Pyra Wireless) arrived just freely moving in a bubble wrap, without any accessories (e.g. batteries), goddamn dirty and squeaky despite being advertised as barely used (my previous one was rock solid) and not working with my eneloops (I can't think of any explanation other than differences in voltage). At first, seller was super friendly, offered me a discount in case I didn't like the shape, etc. When I complained that there weren't the accessories and the mouse wasn't in all that great condition, he accused me of lying. WTF?
