What an absolutely brilliant service I've had from James of 19 Computing in exchanging a faulty (corrupted) Hard Disc Drive from my iMac and replacing same with an SSD. My iMac now performs as it did when I first bought it, probably even faster! James transported my iMac to the 19 Computing workshop from my home, even finding time to fixing my printer before he left! He delivered it back to me within a few working days. 19 Computing have delivered a first class service to me and I cannot praise them enough for their efficiency throughout. Well done 19 Computing, and of course James.
