This keyboard is a complete failure production basically.
The keys hooked constantly and make a liquid and fast typing impossible. I myself use the keyboard only for the couch, where not much is typed. But if you even want to write a few sentences at a time, then you can forget it.
If you have managed to write a few sentences, then wants to delete a letter and hooked the delete key, then makes the whole really not fun anymore.
The User images here in the item description to show this production error to clear.
Letzens the keyboard is slid down from about 25cm and 8 keys are dropped.
Give 5-6 EUR from more and bring something decent.
For other products it is similar to Logilink. I will buy from this company nothing.
