Had a problem – dead MacBook Air 2012 caused by my amateur efforts over 4 hour to repair it It was working ok when I started. Rang Keith. Took it to the workshop. An hour later. Problem solved. Well the problem I created was solved. Mac working but the new part would have been more than I wanted to pay (I am so tight I squeak when I walk) so reinstated. Now 12 months on still working fine. Total cost about £40. Amazing service at any price but this cheap astonishing. Was able to watch while he worked. Promised to review but this is 12 months on and that adds to the reliability of the review.
