Logitech M235 Wireless Mouse, 2.4 GHz with USB Unifying Receiver, 1000 DPI Optical Tracking, 12 Month Battery, Compatible with PC, Mac, Laptop, Chromebook - Grey

Good mouse. Battery life is excellent, I am a heavy user; and the included battery lasted nearly 2 years. I got into the habit of turning the mouse off every time I stopped using it, which probably helped. The switch is on the back but it's easy to do one handed. The USB dongle is very small and compact - I leave mine in my laptop the whole time and I've had no issues with transporting it. You can also store it inside the battery compartment of the mouse as well. I've tried it out on several machines (Windows 7, 8, Linux) and there were no problems with the mouse not working - just plug in and go. The very first time you plug it into a machine it might take a few seconds to recognise it, but after that it's instant.Simple design with just two buttons and a scroll wheel (which is also a third button if you push into it). It looks very elegant. I've even used it for gaming once or twice and it's been pretty good - no noticeable latency caused by the wireless and good accuracy. If you are looking for a 'full time' gaming mouse I would probably get a full size one however. The sensor tracks very well - I've used it on lots of surfaces: desks, carpet, glass, my leg, etc etc and I'm yet to find something that it doesn't work well on.The mouse seems solid and well built, however is a little on the small side. This is great for travelling though. One point - if you have big hands and use a palm grip (whole hand in contact with the mouse - just sort of flopped on top) then you will probably find it uncomfortable. Having said that, I have large hands and the size is fine for me as I use a fingertip grip with my wrist on the desk and just fingertips in contact with the mouse.Overall - a really good buy for the price; recommended for everyone except those who have big hands and are used to resting your whole hand on the mouse.

I originally bought one of these as an impulse buy at my local Tesco. Given where I bought it, I didn't expect too much of it, but it's actually a very decent mouse. It feels good in the hand and is responsive (I can play Counter-Strike with it quite happily). It has a convenient design: simply flip it over to find the switch to turn it on or off, and you can easily slide open the compartment to replace the battery or – and this I especially like – stow away the USB adapter inside it, so you don't lose it during travel. It glides over the desk just like you'd hope, and the scroll wheel isn't stiff or liable to getting gummed up. I also really like that it's just a regular USB mouse, so far as your computer cares. There's no Bluetooth stuff to bother with, you plug it in and it "just works", which is rare for a wireless device.It's a portable thing, so it's quite a bit smaller than your average mouse, but it's comfortable for me (albeit my hands aren't massive). This has replaced my regular desktop mouse, and I am very happy with it. Thoroughly recommended.

I have tried Logitech wireless mice before and the ones I've tried seem to not be very accurate and were overly sensitive. I just want a mouse that is wireless, comfortable to use, and works like any wired mouse would do - not overly sensitive so you're having to adjust the way you use the mouse even on normal mouse speed settings.I'm pleased this mouse works perfectly fine - the mouse speed/sensitivity is absolutely fine, and works perfectly as an every-day mouse to use. A little expensive to me but I am in no way prepared to compromise on a cheaper mouse to find out the mouse speed/sensitivity of the tracking sensor is rubbish and having to send it back.Bottom line: works perfectly fine as a mouse to use every day; although the size of the mouse is a little on the small side - probably to the extent where it can be considered a mobile mouse - but I personally haven't had a problem using the mouse. Not had any reliability issues with it being wireless; but this is having the nano receiver on one of the USB ports on the side of my laptop and all-in-one computer. Aside from the consideration on the size of the mouse, the mouse doesn't offer anything extraordinary - two buttons and a scroll-wheel - with rubberised sides to the mouse. The mouse doesn't feel cheap when you are using it; just the sort of quality you'd expect from a mouse in this price range from a company like Logitech.I've used the mouse in both Mac OS X and Ubuntu and works fine in both environments. Not tried it on Windows, but there are plenty of other reviews here that cover that. In Mac OS X the mouse does feel slower on the same kind of mouse speed settings you'd set in Ubuntu and Windows, but this is how the tracking speeds (the 'tracking algorithm') work in OS X. If the mouse feels slow in Mac OS X, it is because you are not moving your entire hand when you are using the mouse (i.e. you are resting your wrist on your desk). In Windows and Ubuntu, doing this would make the mouse feel way too fast; the reverse in Mac OS X.

This is a great mouse, good price and good quality. Tactile finish and very accurate on the screen. Third one of this product I have bought (for family) not because they broke.

Not a Unifying reciever and is not compatible with other Unifying dongles. I've had Logitech mice and keyboards for eons and it baffles me why they made unifying as standard across all their devices in the late 2000s & 2010s, yet now they sell mice that require dedicated dongles!The mouse is fine if that is the only thing you have plugged in to a laptop and have no intention of changing/using another keyboard. Would not have bought it if the description did not have 'UNIFYINGv in the item description.
