Kensington 64475 Mouse-in-a-Box USB/ADB Mouse (PC/Mac)

With the recent trend towards adding as many buttons as possible to mice, you may find a single button PC mouse a little quaint. However, this mouse has been absolutely perfect for my four year old son, who is just starting to play children's computer games (the excellent Putt-Putt series is well suited for him).

When using a two button mouse, my son would frequently hit the right mouse button, bringing up a context-sensitive menu. This would then lead to unexpected behavior -- windows closing, shrinking, moving, etc. -- depending on where he clicked next. As a result, using the computer was a frustrating and confusing experience for him. With this one button mouse, the problem is eliminated. No right mouse button, no content-sensitive menus.

While it is possible to defeat the right-mouse click menus in software, it requires editing registry values, and affects all users of the machine. Our computer is shared, and the adults using it still need the content-sensitive menus. We plug this mouse into a spare USB port when our son plays games.

Though the documentation isn't super clear, this mouse works just fine on a PC. The single button acts as the left button in Windows.

Worked perfectly on my Power Macintosh G3. Adaptor will always be of use to me long after this mouse has bitten the dust. Lot's of bang for my buck.

This mouse does what a mouse should without the need to go in and clean the rollers every month or so when they get gummed up from the ball picking up dirt from your desk or mousepad. Personally, I don't miss the old rollerball.

As for lead content, I'm sure it's tagged for not using exclusively RoHS components on the circuit board. Wash your hands after using it? Get real. If you have an older Macintosh with an ADB port, the whole computer is filled with lead solder joints as is your keyboard. None of which pose a hazard to you. Just be sure to properly recycle the computer when you discard it so the lead does not seep into the groundwater at the landfill.

While I personally applaud the RoHS initiative, one has to realize what it's for (see above). Just because a product contains lead does not make it an immediate hazard to you - especially when you aren't routinely touching the lead as is the case with this product. If you're very concerned about lead in products, you had best get rid of that old mac (and every CRT - monitor or television - you own because these have a POUND of lead in them!)

This is nothing but a USB to ADB adapter, which is analogous to those USB to PS/2 adapters which sometimes accompany Wintel mice, plugged into a USB mouse with a cheap and cantankerous cord. As Kensington warned me, it doesn't work with the Apple IIgs ADB port. I plan to try the adapter with some other USB optical mice to see what results. If one wants an optical mouse on a classic Mac with ADB, this will be the only alternative (the MacAlly mouse is opti-mechanical). Mac owners with PCI slots in their CPUs will probably be better off installing a compatible USB card.

This was replacement from the company because I old one didn't work well at all.

On the back of the packaging there's a sticker added to the back of the instruction manual which says something about lead in the mouse cord and that California recognizes this as a health hazard and to wash your hands after touching the mouse cord etc...

it's a great mouse but their previous MIB didn't have this problem. I would give it a five but because of this lead issue I won't.

Lastly, it doesn't fit a regular Macintosh Keyboard because the adapter is too long. It can only be used on a Mac pro keyboard. crazy

anyone know where i can get an old MIB?
