The HP Elitedesk 705 G5 Mini computer arrived well packaged and looking to be in good condition, but when setup and used, it would shutdown after 5 minutes. Support from the vendor was time consuming and painful as it is done via email and so took days! It took a call to Amazon to get them to admit that the product was defective and I requested a replacement - a process that was also time consuming and a nightmare both with the 3rd party vendor and Amazon support! So much for their A-to-z Guarantee! If it's from a 3rd party Amazon has no control over the replacement or return process and you are left to the mercy of the vendor. A word of advice, DO NOT BUY a renewed computer from Amazon if it is not "fulfilled" by Amazon! Even so at best it's cross your fingers and pray
