These guys look and are indeed good professionals. I had an SSD installed on my iMac, they did it quickly (less than 60 minutes), staff was polite, excellent customer experience. The only reason for giving them "Normal" rating instead of Good or Very Good was the pricing policy. When I made the initial call I asked what's the price of the SSD and how much they'd charge for the engineering work. They quoted a price, I agreed. Interestingly, the price they gave me for the SSD (Crucial BX100 500GB, 2.5-inch SSD) was over £30 more expensive from Crucial's official retail price (and computer companies are usually getting stuff on different, cheaper, prices). Mac Man's price was £190, Crucial's price is £157. I agreed because I wanted the SSD installed quickly but I have to admit, this wasn't the best pricing (and customer approach) policy. Everybody could check the price of something so offering a massively overpriced SSD doesn't make good impression, especially in the cases when you guys charge for engineering work. You better increase the price for labour rather than give your customers "cheap" labour and make profit from re-selling SSD drives that are available on Amazon. Apart from that, I'd recommend the Mac Man. Very professional.
