I had a very slow laptop that took ages to boot up. Instead of advising me to buy a new one, Damien installed an SSD and added RAM. As a result, my machine is running like new (almost)! His quick response and willingness to repair rather than sell new really won me over, and allowed me to save a lot of money. I highly recommend Tera24 for any IT assistance in Dordogne!
