Logitech M720 Triathlon Black Bluetooth

Advantages: Comfortable mouse for office work. Excellent switchable wheel with fast scrolling only when needed.
Side buttons exactly where necessary.
Universal receiver that does not get from the laptop.
The potential to work with other devices and bluetooth.
Long battery life

Disadvantages: Does not work on glass - in some hotels the tables are covered with glass

Comment: He took to replace the marathon mouse, who served for 7-9 years. All the same, but a little more comfortable.
Great mouse

Advantages: The ability to connect to 3 devices.
High - the palm lies on the mouse, which means that the wrist is not so much strained.
Bluetooth and Wi-Fi at the same time (the transmitter is hidden in the stomach).
And by the way, the transmitter that this mouse in the stomach has is the same Bluetooth adapter that connects up to 6 other devices !! So I was told by the manual downloaded on the Fitz website, when I connected the mouse to the keyboard and to the 380 keyboard. No need to buy extra - and he is not worth 3 kopecks.

Disadvantages: Some kind of it is not a fountain. The wheel is constantly once again scrolling, it does not immediately work, as if every time you need to click "oh, are you already spinning me? And I did not notice here, I'm sorry."
Not silent.

Comment: In general, nothing like that, but I expected more. I will not bear, of course. But serious work with it somehow does not work. And this is more than 3 thousand rubles. My mouse for 600 p. intro mw107G copes better. Although it may unnecessarily carp. After screwing it (with the keyboard on a pair) through the native program, it became possible to jump from one device to another without pressing the buttons with the corresponding number. Just spend the cursor in the corner of the screen, and he is on another monitor. The keyboard automatically jumps too, so, you put the cursor and type. In principle, the video did not lie. Only, as usual, they did not really explain how to do this. 2 weeks I use, but only (from the below reviews) I learned that there is firewood on the office site :))
If you are not critical of working with 3 devices at the same time, find another option. If you have a lot of different devices (for example, homemade beech and etc.) were brought to work, then this is a very necessary thing. Actually, I do not know any analogues. I used to use the mouse wizoutborder Windows program in order to use 1 mouse for 3 devices, but I didn’t connect with each other on different axes, some ordeals. And with this mouse everything is OK.

Advantages: 1. bluetooth smart - can be tied to 3 devices (to 4m - 4th through the unifying receiver, it comes with the kit) and instantly switch between them
2. Power is the usual AA battery (one), and not a proprieritarny built-in battery
3. There is a place in the housing under the receiver.
4. On the Amazon you can buy a case for it.
5. A wheel with high-speed scrolling (for some reason there are very few mice at Logitech with this feature) and tilts (this is not visible in the photo but it is really oblique)
6. the shape of the body is curved, although my hand still does not fit all, but this form is much more like a flat type anywhere MX 2.
73 additional buttons on which you can hang the shortcut keys (albeit programmatically through the driver, but nevertheless it works fine for yourself)

Disadvantages: 1. controversial coating material. Maybe it is nicer than a smooth coating, but if it gets dirty, it will most likely be killed tightly and you will have to throw out the mouse. For me - the most significant drawback of this model.
2. Sensor. Small resolution (1000 is suitable for HD resolution, for fullhd it will not be enough) and the location is not in the center, but with an offset to the side and of course simple optics, not a laser.

Comment: A pretty successful model turned out - according to reviews in the internet, I thought it would be unkillable (the same anywhere mx 2 loses with a built-in battery which, according to reviews, lasts about a year, after which the mouse can be thrown out), caught fire, bought it - but the ambush turned out to be completely different from where I thought - not in the sensor (it is quite enough for office work), and in covering the mouse - it is very easy to kill, and not with scratches but corny to stick with something sticky and everything will most likely not be cleaned, but pity if it were not for that almost perfect mouse for office on the road.
