This company and the seller are nothing but a bunch of RIP OFF and I want my money back.  How can you sell something that half of  the essential keys dont even work? Let me put this in perspective for you all. For example, 10 keys ( f1-f12) DO NOT WORK, but for the  sake of my time and sanity I am only going to cover a few.BRIGHTNESS- when I try to turn down the brightness, it takes me back to previous page and repeat what I already read and the turn up brightness button don't even work at all.VOLUME- I can't turn the volume up or down,  I  every time I press the key to turn the volume down  it goes to a full screen and this mambo jumbo data crap pops up.  The volume up key dont work at all so does the mute button.  If I have to manually turn everything up and down what is  the point of having all these useless keys on here?MUTE- the mute key doesn't even work at either. On top  of that this computer was supposed to be a touch screen too, not the case. I bought this because I saw some good reviews, and it was touch screen supposedly. Y'all must be the ones writing your own reviews for this product or something because there is no way  people didn't catch these issues. BUYERS BEWARE. I DO NOT RECOMMEND THIS: I AM RETURNING  IT ASAP AND I  WANT MY MONEY BACK ASAP.
