David Roster has been a 'Mr. Fix It' for as long as he can remember. Taking apart toys when he was a kid quickly progressed into fixing bicycles for himself and his friends.
As he grew older, David developed a love of all things technical. Naturally, his ability to understand what makes them tick followed and wasn't long before he was able to repair all manner of gizmos and gadgets including washing machines and dryers to iPads and Smartphones.
Reading David's books will help you to do this too!
