Prehistory
Actually I fell in love with this clave for a long time. Or rather, when it was announced. In fact - it was the keyboard - correcting errors and improving the wired version. And I liked it. And she was wireless.
In general - as soon as she appeared in our town, I ran and bought.
Read the review and my impressions under the cut.
Keyboard Characteristics
There are no clear characteristics on the site, so I will write myself :)
Type: full-size, with a digital block (105 keys)
Wireless: yes, unifying (2.4 Ghz, mini usb receiver, universal for multiple logitech devices)
Dimensions (W * D * H): 450 * 200 * 15 mm (approximately, measure by line)
Backlight: yes, white, 4 levels + light sensor + proximity sensor
Unpacking and packaging
The box looks like this:

When unpacking, we see this:

The package includes:
- Keyboard itself
- Micro USB charging cable
- Instructions
- Receiver (unifying)
')
As you can see - the package bundle for this device is not very abundant (with its price being 100 euros)
Feelings and impressions
The keyboard is made soundly, I can even say - very high quality. Backlash and other things - not noticeable. Materials are only the best. On an unremovable palm rest (indispensability - sorry, this is a minus) and the top - soft-touch plastic (matt !!!). Very pleasant tactile sensations from him. Similar plastic - keys. The edging of the key block is glossy plastic ... which is beautiful - but a minus.
Keys with short move, but clearly positioned. There is no space between the keys (like on laptops of ala makbuki or sony) - this is an amateur. However, the keys themselves are quality, quiet, lightly pressed.
The backlight is adjustable (4 levels) + light sensor. The backlight is white, the letters on the keys (both Russian and English) are laser engraved, the backlight shines through them. All OK.
Here is a picture of the backlight:

A separate thank you goes that the keys are still made standard - normal del, large enter ... Only with the left cipher (it is short) a bit namutili, but IMHO is the lesser of evils.
I liked the similar wired version of the illuminated keyboard FN key - which is the functionality of F1-F12 and further. Conveniently. And the Win key is free - which is correct because on my last keyboard (steel series 7g) the key was made instead of win on the left - and it was very inconvenient.
By the way, here's a photo of the comparison of visual dimensions (the smaller steel series lies on the k800):

Of the extra buns - charging does not require interruption of work - and the standard wire (microUSB) - so there will be no problems with charging. True, this very charge will have to be done quite often - the manufacturer declares "up to 10 days of battery life." I can’t check it yet - I don’t own so much. But the logic, why so little, is clear - the backlight is eating energy, and, apparently, considerable ... I hope if you cut down the clave for the duration of inactivity, it will live longer. In any case, it is easy to charge it, and this is a big plus.
Conclusions, pros and cons
Pros:
- Beautiful

- Price of 100 euros
PS Ask, ask questions about the device - I will answer with pleasure.
