The mouse is 1000dpi optical but feels like a Laser. It moves on a smooth wooden desk surface and without a pad. Good. However, it does not sync well with the USB dongle, since the dongle and the driver have to sync with the keyboard at the same time. In 3D games, you get burned. And if you don't set the Windows Energy Profile to not turn off the USB ports, then you get burned twice. Also, it doesn't have Left/Right on the wheel, which I find essential. It also consumes quite a lot of batteries. I have the Triathlon 720 and I can't remember when I last changed them, with daily use and gaming. For office use, yes, it's typical. Not for fast motion and fast keypresses. I kept the mouse for the country house and there I put another older keyboard with another second USB: the legendary Logitech Desktop Cordless LX-700 (optical) and I found my peace. But for €50, what are you paying for? (update 4/3/2026)

I read the reviews and I am really amazed at what some have said.... I have had this set for almost a decade and it has gone through countless hits, endless hours of gaming, and the clacking of the keys, I've only changed the battery 1-2 times and it generally works incredibly well..! The only downside is that it doesn't have lights to see if the CapsLock is on, etc... I got it back then on sale for about 35, I think, and after all these years it still holds its value... For those of you who want it for gaming, office work, etc., it works perfectly with your eyes closed...!!!!!

You cannot set the command you want on the additional buttons. Whatever it has by default. The previous model worked perfectly. I bought almost the same one so I wouldn't have to deal with it. Useless. Logitech support is nonexistent.

Good keyboard with a nice typing feel. The major downside is that it doesn't have backlighting on the caps locks. It has very good battery life and the mouse, although small, does its job.
Don't buy it if you play games, it's more suited for office use.

Medium quality keyboard/mouse set with cheap plastics and a lot of noise when typing. The huge downside for me is that it doesn't have a caps lock light, so you don't know if you're typing in lowercase or uppercase, especially in passwords. Considering its price, I find it unacceptable. Overall, it doesn't impress, it just does its job without demanding high quality or ease of typing.

I bought 2 sets for the computer. There is no indication for Caps Lock....how much battery does a light consume? The on/off is at the bottom of the keyboard. If you open/close it every day, it becomes annoying.
Cheap plastic. After one year of use, some keys do not work properly. The mouse is uncomfortable, with a bad scroll wheel and small. I do not recommend it for office work, only as a temporary solution.

All right, but not for 40-50 euros, but for 20-30 at most.
Although the keyboard is simple and soft, it is quite "plastic" in feel and quality.
The mouse is inexplicably small, and I have another one otherwise it would not be practical for prolonged use.

No matter how many years pass, I will never find a keyboard like the Microsoft one I had 12 years ago. None that has passed through my hands had the same button quality. I would prefer this specific one with a slightly larger gap between the keys and a slightly higher height for better typing feel with a blind system. I would also like there to be an indication for caps lock/battery.

The mouse will cause damage to your hands (tendons, etc.), unless you are small and as a result it will fit in your palm! I will buy another one before I get hurt

The mouse is tiring, not only because of its size but also because of its overall feeling. Even in the much cheaper MK220, there is a better one.
The keyboard without caps/num/f lock indicators, and you can't call it silent.
1x AA battery for the mouse, 2x AAA for the keyboard.
On/Off switch on both.
Good range.
However, the price is unreasonably high (even though it's a brand like Logitech), when for half the price you can currently buy the Wireless 800 from MS, which is overall better.

It is very convenient, it has a user-friendly keyboard and is very comfortable with a very nice feel when working with it... the mouse is small and elegant and does exactly what it needs to do. Its only drawback is that it does not have indicators for caps, num, and f locks, but after a while, you get used to it!
Another drawback in my personal opinion is that it does not have a place to rest your hands on the bottom of the keyboard, so after a while, your hands start to ache in the wrists... it's also a habit because I had a keyboard with support at the bottom for the hands for years, so it will take me a little while to get used to it, but otherwise, it's worth its money!

Truly the best I've ever had in my hands! Silent, amazing response, the keys are an extension of the fingers.. With great durability! Several helpful buttons as well, such as next song, pause, play, etc.. Its only downside is the non-illuminated indicator for active functions like caps lock, Num lock, etc.. You get used to it!
The mouse is also excellent, comfortable and fast... maybe a bit tiring for very large hands since it is mini.

I have this amazing set for 3-4 years now and it's brand new. The keyboard has very good feedback and is quite comfortable, just like the mouse
