Ok but poor quality keyboard mouse

I had not paid attention to the fact that there was a mouse that came with the keyboard, so it was a pleasant surprise but the least we can say is that I quite quickly became disillusioned. For starters, it is not very nice, quite heavy and unwieldy. I took her on vacation because it is relatively convenient (wireless) but I did not like at all to use.

She broke down after ten days. First of I thought the supplied batteries were cooked but actually not, it's just HS and I do not know why. Compared with my logitech small carrying pouch and USB Port a quarter of centimeters thick, there is no comparison.

The keyboard meanwhile is correct and the support for the hands is very nice but he also has some real drawbacks.
For starters, I do not like how the buttons are positioned, I can not get used to it and yet I'm working on 4 different ordis commonly (HP at work, a logitech at home and two laptop different brands. There is a real pain, my hands have to make lots and lots of movement to access keys, the "Clear" key is very high, so that I press enter to almost one in two .

Finally, the fact that it is the front of the keyboard that is lifting forces me to sit up enormously, which hurts my back.

So excellent comfort wrists, but general discomfort and annoyance for use.
Therefore tested, but surely not adopted!
