For my iPad I use a Periboard 804. Super! It was clear that at some point I wanted to make a mini-keyboard for my desktop. The choice fell on the 410 H, but unfortunately the quality was not comparable. Some key creaked and raked. I picked up the corresponding buttons from, tried the leadership of X-type scissors adapt and eventually used a drop of oil. First remedy, then made the keyboard only "rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr" and then do nothing more. My fault! I ordered the illuminated version: 411 H
The lighting: impressive. Processing: Needs improvement. Now creaks and raking it in another corner. I have lifted out two keys and tried to set up better. It has partly succeeded. I would like to pay 10 euro more and get a perfect keyboard of this type. Cheap is not always good! Oil I no longer use.
