I'm currently using this mouse on my Ubuntu PC, and have also tried it on Solaris and Windows. It has an excellent response time, never lags or freezes, and wastes very little battery. I'm currently powering the mouse with two AA UNiROSS 2700mAh NiMH batteries, which I charged less than a year ago.
The mouse came in two parts: one is the USB receiver that has a metre of cord, and the second is the wireless mouse. The receiver is quite big, not the sort you would use with a portable computer (i.e. netbook or notebook). That being said, the signal quality is always close to 100%, and hasn't ever dropped below 80%.
The mouse doesn't come with many buttons, or many extra features, but the range of customisable features is good enough and avoids confusion, which would have been due to too many buttons. The mouse has a standard wheel between the main two buttons, but this wheel has on extra feature, which is that it moves side to side. I find this feature very useful for moving between tabs while browsing and a number of other uses, depending on the active program. The two browser function buttons are useful if you like using more buttons, but I only used those a few times, and turned them off in Ubuntu, because I prefer to use the keyboard for most of the browser functions, e.g. to go back Alt + Left Arrow, forward with Alt + Right Arrow, etc.
I think the mouse is just the right size for everyday use on a PC, especially if the PC runs Linux. I used this mouse a few years ago with Windows and Solaris, and although it performs well, the performance is much better on Ubuntu 10.04. I haven't yet tried it on Ubuntu 12.04, which I have a live DVD edition and am considering writing a review about after a few more days of use.
I think the reason behind this mouse performing better on Ubuntu, is that the operating system can be customised very much to the user's standards. Although the mouse is manufactured by Microsoft, and their own driver software maybe designed more specifically for the device, my own experience shows that this mouse works better with Ubuntu. I've got the mouse receiver plugged in via a USB to PS/2 connector to the standard green PS/2 mouse port on the computer. I've never had problems connecting USB mice via PS/2, but there may well be USB mice out there, which won't work through a PS/2 connection. I've only had problems with USB keyboards connected through PS/2, most of which the computer doesn't detect at all.
When setting up the mouse, and after replacing the batteries, I found that to be the time I need to press the small connect button on the mouse, while pressing the larger connect button on the receiver. The batteries are easy to replace, but they require some extra effort to remove, for which I use a small flat screwdriver it get one battery out. Once that's out, the other one comes out easily. Placing batteries into the mouse is an effortless process, so no tools are required at all. You simply insert the batteries one at a time, sliding them into the holding positions.
I've used several lighter mice by Logitech and Microsoft, and found this one to be far better for control and better usability and durability. Out of all wireless optical mice I've used, I'd say this one is probably the best in performance, energy efficiency and ease of use.
The mouse works using optical technology, so it probably wouldn't work well on a reflective surface. I've never used it on a reflective surface, so I've never face such problems. I would recommend this mouse for any PC user, but wouldn't recommend it for anyone carrying around a netbook or notebook. Notebook and netbook users would probably prefer mice with smaller receivers, which would save more space in a carry case, and would require less space to operate.
To sum up:
The best Microsoft wireless optical mouse I've used, highly efficient and works well with at least three operating systems, which I've tried it on. Its powered by two AA batteries, and operates wirelessly via a USB receiver, which can be connected through a PS/2 connection. I recommend it for PC users, but not necessarily for portable computers.
I bought the Microsoft IntelliMouse Exporer in the colour Cobalt Blue 5 years ago, and I haven't felt the need to replace it since. The mouse is attractive, comfortable and, for a mouse, feature rich.
It features the standard left and right mouse buttons, but is complimented by a mouse wheel that can scroll up/down, left/right, and also be used as a click button. There are a further two thumb buttons positioned on the left hand side of the mouse that are used for moving forwards and backwards in Windows or IE/Firefox/Chrome. This feature is particularly useful for gaming, notably FPS games, since reloading and changing weapon can be integrated onto the mouse itself, minimising the need to use the keyboard.
With respect to performance, it has waned slightly over the years. Initially I could use the mouse anywhere in my room, and on any surface. Now, it struggles on shiny surfaces and occasionally fails to find signal when it's just a couple of metres away. Whether this is a failure on the part of the mouse, or simply the base unit/additional wireless signals I'm not sure, but it perhaps detracts from the reliability of the mouse somewhat.
It is a good mouse and well worth purchasing, for the average e-mail/internet user, it's perhaps unnecessary, but if you use your computer for long periods of time and for playing games, this should be your mouse.
I bought this mouse about 3 months ago in a special offer and was extremely pleased when it came through the door. It looks great, and fits very nicely into your hand. At this time I had an old computer with a USB PCI card, and when I tried plugging the mouse in, although it was recognised, I could not get it to work. This was a bit of a dissapointment, but I had been planning on buying a new computer, and rather than send it back I decided I would hold out till then. So, last week I got my new computer, and very nice it is too (see my op on Aldi). I jumped straight in the deep end, and plugged my Wireless Intellimouse Explorer in. It was immediately recognised by Windows XP, and I could have used it like that without installing any software. But I decided to install the software anyway. This has a very easy to use interface, and allows you to change what each of the 5 buttons does amongst other features such as auto-select etc. So my mouse was fully configured. I tested the mouse on lots of different surfaces, and it seems to work well on pretty much anything but mirrors and you can use it from about 5 metres away before it becomes unresponsive! I had read reviews that the Microsoft optical mice were a bit slow and not particularally good for games, and although it seemed to be working very well in windows, I decided to test it out. I was hoping this would not be a problem as I play alot of First Person Shooters, and therefore use the mouse alot. So I tested it with Quake 3 and Return To Castle Wolfenstein. I did not have one problem. The responsiveness was too much to start with, so I had to turn the sensitivity right down in the game, and if anything the responsivness was better than with my traditional mouse. The early reviews I later found out were on the older optical mice, which only scanned the desktop 1500 times every second. You would think that was enough, but obviously not. The mice now scan at 6000 times every second
and they work perfectly! I would definately reccomend this mouse to anyone, and I definatley think it is worth every penny of the £40 I paid for it.
