Bought the same for testing klaviaturka A4 KV-300h.
The biggest two disadvantages:
1) long pressing Enter in one row the height of the layout is strictly not Cyrillic. Just put the letters of the Russian. Judging by the font of Russian letters on the device and no on the package and documentation inside any Russian texts I will assume that the plant she left without caused to national symbols. As a result, instead of enter, I almost always press "\".
For years, I'm accustomed to touch-typing and click on enter in General without thinking where he lived for many years. And then... and to be retrained will not — rest technique has a European layout.
By the way, I know that there are people looking for just such an "American" layout — they will be fine.
2) Noise so that I'm afraid to Wake the neighbors;
Of course, pressing the tactile do not in any way similar to the required.
However, it should be noted that, in General, to print very conveniently, in spite of the above. The keyboard is heavy and is very hard, which is good news. Usb ports — well... I don't know if I'll use them ever. For me it would be significantly better to have wireless connection instead of ports. Another plus — during printing, the plane itself, the keyboard does not bend, which is also very pleasing.
The rise of keys is too big. Despite the fact that it's not a membrane keyboard — special experience she leaves. Barely remember anything noisier this keyboard.
And, Yes, it is worth noting that the keyboard color on the photos are a bit false — in life it is significantly darker, which could not fail to please.
On the other hand, for the 500r?..
Conclusion: it is safe to order, say this is
and easy to engrave Russian letters. Unless, of course, do not mind such a configuration, Enter-a.
