Packaging and contents fit with me not together [Update]

Part Number on the packaging 0A36407 due to this offer. This should be 3.0 1200dpi laser mouse loud lenovo.com Bluetooth. In fact included in the (very original and undamaged looking bulk) packaging was a Lenovo Bluetooth Laser Mouse P / N 0B58445, FRU P / N 03X6582. It is probably an older model with 800dpi. The serial numbers (S / N) on mouse and packaging also do not match. The drivers under support.lenovo.com/us/en/documents/pd024641 also works for the "wrong" model. To avoid dropouts / trailer had in Device Manager | Bluetooth Radios | ThinkPad Bluetooth 4.0 | Power Management the option "Allow the computer to turn off this device to save power" be deselected. (Win7 Enterprise SP1 32-bit, Lenovo X230)
Otherwise, the function is as expected. The supplied, new (!) Energizer Alkaline AA Batt. are after 2 days at 89%. Operation with Varta 1900mAh battery was possible. (Addendum: Does not work on glass surfaces). Hope for the replacement of the current, correct model ...
[2015-04-15] The replacement did not contain the offered model 0A36407 but again 0B58445. Again I Amazon were P / N (0A36407) and S / N on the bulk packaging not the same ones used on the mouse itself. Reiterated this fact. What is the experience of other customers?
