I purchased an HP Elite 8300 Ultra Small Slim High Performance Business Computer PC (Renewed) and have had it up and running for a little over a week. I have always purchased new PC's but decided to try a renewed unit for a change. The install and loading programs went with no hitches and within 2 hours I was up and running. I noticed a slight glitch and contacted AST technical support for assistance. Instead of calling I sent an e-mail advising support of my situation and asked for a call back or an e-mail with the answer. Within 12 hours I had an e-mail with a video explaining how to correct the issue and was told that if I needed further assistance to let them know. Within 30 minutes the correction was made with no further problems. The next day I had a follow up e-mail from technical support making sure the situation was taken care of. Very pleased with the PC and very pleased with the quick response of AST technical support. Leonard Long
