The Road Warrior Review - Kensington Ci95m Wireless Mouse With Nano Reciever

One of the newest models in Kensington's slim line family of computer mice, the Ci95 Wireless Mouse With Nano Reciever features a slim profile - up to 30% thinner than is typical with computer mice. It is also a smooth and slick performer, gliding smoothly across my mouse pad.

The Ci95m is however a bit heavier than the older model Ci75m which it physically resembles, due to using AA batteries (included) rather than the older unit's smaller AAA cells. The AAs have presumably been given the nod because they offer longer battery life claimed to be up to six months. My personal preference would be to live with shorter battery life in order to get the lighter weight, but that's a subjective preference and Kensington goves you the choice.

Also new with the Ci95m mouse, and indeed its marquee feature, is a new "plug and stay" "Nano" wireless USB receiver dongle which is so minuscule that in most instances you should be able to leave it in one of your 'Book's USB slots even when the machine is in its case or sleeve for transport.

Note that the Ci95m Wireless Mouse is not a Bluetooth device, but operates on the 2.402 - 2.479 GHz frequency with a nominal range of up to 10 feet. This has its advantages and disadvantages. On the one hand, you don't have to be bothered with the tedium of Bluetooth pairing and wake-up lag; on the other, it eats up a precious USB port, and the little receiver module is another loose bit with the potential to get lost - especially this extremely tiny unit.

A few more notes on the Nano receiver, the picture shows how small it is compared with the Ci75m mouse's receiver. While the latter stows in a recess in the base of the mouse when not in use, the Ci95m's Nano receiver is carried inside the mouse housing in a recess with a magnetic holder situated between the two battery bays. With the halves of the mouse housing also held together magnetically, access is quick and slick.

The Nano receiver is incidentally not compatible with other Kensington products like the Ci75m wireless mouse and the Ci70 Wireless Desktop Keyboard and Mouse set which use a different 27 MHz frequency and have a range of up to 30 feet.

I found the Ci95m comfortable to use, with its low profile contributing to keeping your wrist angle flat as well as looking cool and contemporary. The sides and palm contact area of the mouse housing are clad in a rubbery traction material for a positive grip.

The light action and relatively short travel of the mouse buttons are much appreciated as well. The mouse's split top panel flexes for the left/right button click functions, which have a positive feel. I also like the scroll wheel, which is clickable for a third-button function and likewise has a positive, high-quality feel, with perhaps just a bit stiffer resistance to rolling than I would prefer.

Happily, the Ci95m Wireless Mouse requires no driver installation or other software, and is supported by OS X default mouse drivers.

As for wireless performance, the mouse is instantly recognized by the system without having to muck around with pairing connections like you have to do with Bluetooth mice. Unfortunately, this mouse, like all wireless mice I've ever used, is afflicted with a degree of latency in response to user-input. I'm happy to report that there seems to be progress on this issue, and this recent generation of Kensington mice is the least troubled by this symptom of any wireless mice I've sampled to date. It's just a tiny micro-millisecond lag between the time you move the mouse and when the movement registers with the cursor, as opposed to the right NOW response you get with wired mice that bothers some folks more than others. The most significant aggravation associated with this for me is that it causes me to overshoot onscreen targets. It might also be less of an issue on machines faster than my old 1.33 GHz PowerBook G4.

Actually, after a few days of using these mice, I begin to reflexively compensate for the wireless lag, which renders it only a minor annoyance.

If you prefer a hard-wired mouse for maximum precision, Kensington makes a notebook mouse with a retractable USB cord, the Ci25m Notebook Optical Mouse, which sells for a modest $19.99, looks great, and about which you can find out more here.

The Ci95m is a cleverly designed little rodent, one of its coolest features being the aforementioned magnetic closure clamshell housing, which opens to reveal the battery bay and hideaway Nano receiver storage by simply pulling the cover and bottom modules apart with no screws to remove or latches to manipulate for literally instant access.

Speaking of sleep, one minor glitch I experienced is that the mouse drops its connection when the computer goes through a sleep-wake-up cycle. The drill to restore the connection is simply to hold the left button down for a second or two.

The Ci95m mouse has a laser sensor, presumably 1,000 dpi although I wasn't able to confirm that spec., and I expected it to feel "nervous" with that high a resolution, but it doesn't. Other than the aforementioned wireless latency issue, the mouse is nicely responsive and precise.

Overall, this mouse has a high standard of finish, the feel of quality about it, and a five year warranty to back up the impression.

While it is perfectly usable with desktop computers, the Ci75m makes an excellent notebook mouse; its slim profile and light weight make it easy to take along on the road in one self-contained package with the wireless receiver stowed in the mouse body. Good stuff!

• Plug-and-stay nano receiver is so small you plug it in once and leave it in.
