The product was delivered on time but only comes with 8 GB memory instead of 16 GB.  Aside from this the product works like brand new.  Performance is great though it weighs more than that advertised.  The problem was brought to the attention of the vendor.  They were surprise and Thom Dixon their Customer Service Manager offered to fix the problem.  As no memory was available during that time, a USD $50 rebate was offered instead.  I accepted as I needed the additional memory.  After several weeks I was contacted again by Thom informing me that they have available memory and offered to send it to me for free even after the rebate.  After receiving the memory, I installed it and it work smoothly.  Thank you Thom for a wonderful support.  Highly recommended!  Would buy again from them in the future.
