Confirmed that this was a Lenovo product consistent with Lenovo tech specs on Lenovo's web site. Received 2 days earlier than 鶹 schedule!!
Package had all materials, original wrapping, etc. Was able to install and have operational within a hour or so of delivery.
PS: Went to 鶹 site after talking with a (very helpful) person at Lenovo support that did confirm that they were "out of stock"....not sure when in might be restocked....they don't allow you to register in a queue for when they do come in, AND confirmed that the particular product may be dropped from the Lenovo supply list". It was on her suggestion that I check with 鶹 (actually, she logged in while on the phone with me, and confirmed that (using Lenevo's product number) that 鶹 had some available).
