Also new to the cordless mice is a nice LED indicator of battery strength. No longer will you need your computer running to know how much power is left in the mouse. Three green LED indicators show you the power left in the mouse. The three LEDs do turn off when the mouse hasn’t moved for a bit and to also help conserve power, you can manually switch the mouse off on the bottom. That way you will know for sure that the mouse isn’t draining away the batteries when you are away from your computer. The mouse will turn off by itself after a period of non-usage too. Either way, you can either turn it off manually or just let the mouse sit.

Now you will notice that there is no battery compartment on the mouse. The previous cordless mice allowed you to use your own NiMH rechargeable batteries. The MX1000 now uses a lithium-ion battery, which Logitech states does not need replacing. Well, what if you run out of juice you say? Logitech states that you can recharge the battery for a full day’s use in 10 minutes. And a full charge will now only take four hours. That’s a big change from what it used to be. The switch to lithium-ion also affords a longer battery life, averaging 21 days now. To help alleviate the battery memory problem, the mouse stops charging when it is full. The weight of the mouse isn’t too much more than the MX510. It weights 171 grams, compared to the MX510 which weights 125 grams (167 grams counting the cable) or roughly 2 ounces more. Lifting the two, you do notice a slight difference in weight but nothing substantial.

As with most cordless mice these days, the cradle doubles as the receiver and recharging station. The cradle’s design has changed as well with the base not being as large and the new cradle also has a nice little back to rest the mouse on. The connect button is located on the front of the base if you need to reconnect the mouse. While I’m not a big fan of brick power plugs, the brick power plug on the MX1000 isn’t nearly as bad and is built more horizontally so that it doesn’t interfere with the other plugs as much.

So let’s get to the most radical change that this mouse exhibits over all others. This is truly a laser mouse and on the bottom, there’s a little line that states it’s a class 1 laser product. With optical mice, a red LED sensor illuminates the surface and an optical sensor takes pictures of the surface at certain intervals. The laser works in the same way except, of course, it uses a laser to illuminate the surface instead of an LED. The differences in the pictures are what drive the mouse movement.

Now regular light is what you call incoherent light. They are made up of many independent light waves. They also produce lights of many different colors. Laser, on the other hand, is coherent light. The light is made up of identical light waves and produce light of one color. Because of the nature of the laser, you can focus the light easier and in a smaller area than regular incoherent lights. A good example is shining a flashlight and a laser pointer. With a flashlight, you can see the light expand greatly as the surface you try to illuminate is farther away. The laser pointer is a lot more focused if you would shine it from the same distance.

The MX1000 does away with LED and uses a laser. The familiar red glow you have come to get to know and love is now gone. Using a laser illuminated surface, the mouse sensor can detect tiny changes on a surface that an LED illuminated surface cannot. It can see smaller imperfections in a surface. The peaks and valleys on a surface need not be as great when using a laser. The sensor detects 5.8 megapixels of data every second. Below is a comparison of the differences in pictures between LED and laser.

To test this theory out, Logitech provided three very glossy surfaces with the mouse. Testing the surfaces with various mice I had from Logitech’s line and Microsoft’s line, none of them could detect any changes when I moved them. In comes the MX1000 and the three glossy surfaces are easily readable by the mouse. I was able to move the mouse without any problems on the three test surfaces. It still won’t work on true reflective surfaces but the laser allows for a wider range of surfaces to be used.
