Received a well refurbished product and would definetely recommend this.Purchased the USDT (aka USFF) 8300 . It's a perfect size for my use......-cleaned up nicely by the refurbisher and I'd rate the cosmetic condition as an A--mechanically and electrically no issues-came with Win 10 PRO ready to activate- that's a huge cost savings-keyboard and  mouse are just average but fully usable-packaging was great A+-A+ for overall product.  Would buy another !!
