This mouse is great to carry with your notebook computer. I have a G4 Titanium running Tiger and this mouse works well in OSX.1- It comes with a small black pouch with two compartments were the mouse, the BT dongle and the charger can be transported without loosing them. This is a good thing since all of the items are small.2- It has good reception, I have used this mouse as a remote to run a presentation 4Mt. away from my computer without any problem.3- Very precise - 800 DPI- very quiet.4- Nice design, good construction. It is not a flimsy product. it has an on-off switch5- It may be too small for some people. I believe is a great design, very comfortable.6- The BT dongle is great, it is very small. For instance the microsoft's mouse and BT dongle are big.
