Having just purchased a Boeder sm@rtmouse at my local 'Makro' store, for the piddling sum of £12.99 +vat, I was very pleasantly surprised . The Sm@rtmouse has bothe horizontal and vertical scrolling wheels, both of which can be programmed to scroll any number of lines at a time. ( careful not to set this too high though, pages can go past too fast to see ). This mouse also has a very useful thumb button which can be programmed to produce a magnifying square of whatever size you want, and your choice of magnification, under the cursor. Just position the cursor on whatever you want to magnify and Presto. All in all, an excellent buy for the money.
The boeder wheel mouse is one of the cheaper alternatives to the microsoft versions, and after nearly a year of intensive use, a good alternative. This mouse has two wheels, both the normal vertical wheel, and a second, rather less usefull horizontal wheel. Support for the wheels is good, although does require a system tray utility (that makes eight at the moment..). The mouse is comfortable in use, moves smoothly, and had proved to be reliable. If there is a design flaw it lies with the third button. Rather than having one of the wheels act as a button, here the third button is on the left hand side of the mouse, and falls naturally under the thumb of a right handed user. This makes it useless for the left handed, and is oddly awkward even for the right handed, not to mention very easy to forget about. This mouse has passed the key test - reliability - and is still going strong long after my previous mice have given up and died.
