I took my BigMac into the shop which was old, running extremely slow and was just a nightmare to use. Following a detailed consultation with Gareth and suggests on what was the problems - I accepted the recommendations. Once the repairs/upgrades was completed, following a short demonstration in the shop I took my Mac home, the cost was realistic for the work and upgrade. Once home I plug in the machine worked perfectly, I have now got a BIGMac, that works faster and feels like new. Thank you so much for a fantastic job - highly recommend without hesitation.
