This item does look "excellent" on the outside.  But after only a couple minutes of doing nothing in particular with it, the T470 laptop always crashes to a blue-screen error.  Last week, I spent over an hour with the Amazon help center as instructed on the page enclosed with this laptop.  They could not help, so they said they would forward my problem on to the seller, who'd get back to me within 48 hrs.  A week later, the seller has not contacted me, and now, I am returning the laptop for refund.  Purchasing this thing was a waste of many hours of time.p.s. the Quality-control checklist that the seller provided with the laptop just showed check-marks that OK's  everything, even for features that the laptop does not actually have.  Obviously, somebody in their quality control department fills out forms and just pretends to do their job.
