Outstanding work on adding an ethernet cable that allowed me to avoid a wireless connection and get a much faster and more stable connection for my gaming system. Great service, knowledge, and communication.
My computer was running at turtle speed. Josh ungraded my hard drive and added ram and now it's running quicker than it has in over 2 years . Totally recommend his services.
