On December 12, 2020, I purchased from Skytech LLC what was described on the Amazon website as a refurbished HP central processing unit.  I noted that it came with a generic-looking keyboard that attached to the CPU by means of a cord with a USB connector rather than a jack.  It also came with an generic-looking optical mouse that attached to the CPU by a cord with a USB connector rather than a jack.I ordered the CPU to replace a 12-year-old  custom-built CPU with a failing disk drive.  When a rather large, heavy box was delivered promptly, I was impressed.  However, when I opened the box, to my surprise, it contained a large foldable garden cart.I immediately called Amazon, and the next day Amazon picked up the garden cart and deliveredthe item I had initially ordered.  What I received was a NEW HP CPU with the keyboard and mouse as described above.I have been extremely impressed by the CPU; it has a solid state drive that boots up rapidly; using the CPU makes surfing the Internet a simple, efficient experience.The mouse works well, and I have no complaints.  The keyboard, however, has proven to be problematic.I cannot use my new HP CPU efficiently or effectively because of one relatively small issue with my new key board.  When I type ANYTHING, letters repeat rapidly unless I use a very light, very slow touch.I have tried adjusting settings in Windows to no avail.  I cannot adjust the keyboard sensitivity so that I can type quickly and accurately.  When I went online to see if there was any kind of improved keyboard driver available, I was disappointed to discover that the brand label on the keyboard was a fake.The keyboard I have was labeled "AST."  AST is a French manufacturer of computers and computer-related items.  My keyboard was made in China.In principle, I have nothing against inexpensive computer equipment made in China.  However, this particular keyboard is significantly restricting me in my ability to use my HP CPU.  I would be using my previous Logitech CPU except that the wireless dongle it originally came with accidentally went through the wash in a coat pocket and of course does not work.Generally speaking, in the future, I would (after three months of using my new HP CPU) say that if you want a useful, non-frustrating computer experience, choose a vendor to buy from other than Skytech LLC.
