Have decided in the first place because of the Bluetooth connection to this notebook mouse, because Bluetooth mice are in extremely short supply in the market. However, the modifier keys were important to me. The Bluetooth connection worked flawlessly with the integrated BT module of my Asus netbooks. Unfortunately, the other implementation is so disastrous that I have returned the mouse again: The mouse wheel does not lock, but runs without resistance through - as image indexing useless; to zoom in / out Word documents (with CTRL) is good's also nothing. The final decisive then gave the impossible positioned side buttons. Location wise this therefore can be reached only with the 1st or 2nd part of the finger ... not at all. Has anyone actually times the product tested before it went into production?
Grudgingly I have followed the Logitech Anywhere MX added myself. Unfortunately, I have now again a dongle (very small) on your netbook, but Logitech easily understood on ergonomics: The mouse wheel is top, the buttons are accessible and also the mouse even works on glass surfaces - nevertheless, with BT they liked even better. ..
