Microsoft Bluetooth Wireless Laser Mouse 8000 - Ergonomic Design for Laptops & Desktops - Perfect for Office Work, Gaming & Travel

I used the original Microsoft Bluetooth mouse, several Micorosft wireless mice (not bluetooth), and a miniature laser 5000 for notebooks from Microsoft. This is easily the best I've had and here's why:1) on off switch - worth mentioning twice2) invisible laser very accurate3) works on every surface I've tried4) on off switch -- if you're a traveler like me and you prefer a full size mouse, this is a fantastic option5) rechargeable6) can take a regular AA battery if you aren't in a place to recharge7) energy efficient (2 weeks on a charge)8) looks good9) the wheel is very smooth and silicon10) the wheel tilts left and right and you can push as a button although the pushbutton is a bit hard as another reviewer commented.11) if you're a home user the recharging base is fantastic, looks cool and very easy to plug set the mouse on for it to charge12) Full sized -- I love full sized mice and with the on/off switch, this is a wonderful laptop traveling mouse13) BLUETOOTH -- this is huge if you have a laptop or desktop replacement with built in bluetooth....Microsoft includes a bluetooth dongle but my mouse mated up perfectly with my HP laptop and with my Dell. Bluetooth is a standard so the mouse should mate up with any bluetooth laptop. With a bluetooth laptop, I don't have to worry about dongles or wires or anything like that...the mouse just works.What I don't like about this mouse:1) the side minature (supplementary) buttons are either hard to use or unusable especially the right hand side one, haven't figured out a real way to click it. I can use my thumb for the left one. Although with the other mice were really right handed mice and this one is more of an ambidextrous --- in the other mice, if you were left handed, you were out of luck unless Microsoft made a left handed version of the mouse. With this mouse you get one auxilliary button that you can click with your thumb if you're a lefty or a rightie...just a thought. Microsoft might have just split the difference in the design to create an ambidextrous mouse that isn't perfect for the right handed person but which provides one thumb auxilliary button for the left handed...2) the charger should be able to plug in directly into mouse but with the options of taking a regular A battery and with the long life of battery this is almost a nonissue3) when I bought this mouse it was too expensive but its dropped some, I imagine it will continue to dropOverall,I'm very glad that the people at Microsoft people listened to the users and made this pretty much the best ambidextrous wireless bluetooth mouse.
