Review by grades:
Design: 1
Processing: 2 (can be the very top buttons do not take out and poorly cleaned)
Operation: 2 (so that some keys appeal, one must sometimes vigorous press it)
Programming the keys using the software: 1 (it's in the software all explained in detail)
Value: 1 (can easily keep up with the more expensive keyboards)
My conclusion: cheap keyboard with 2 little quirks that can be accepted by almost everyone for this award)
100 percent buy recommendation !!!
