I think it's harsh to give a very negative rating to this site.
Pretty clearly a legit computer repair business, specialising in hardware repairs & simple solutions to software problems.
I'd be pretty confident he'd turn up on time & do what he said.
Looks like in his efforts to find content / make money, he linked to registry 'cleaners'. those links are now dead, suggesting he has learned something.
There's no getting round the fact that linking to those sites in the first place doesn't give a good message about the technical level of the business
The below quote is a testimonial comment from one of our customers.
I have found the services of MJS Computers invaluable for the last 9 years and will definitely continue with Michael for the foreseeable future, as the service comes in a personable as well as competent manner.
As a person who is disabled it was good to discover someone who was able to support me at home and was sensitive, not only to the PC needs of the disabled, but to the programming needs I have particularly as a musician.
Whatever is new, MJS Computers is quick to learn and introduce to his "regulars".
Their website is a mine of valuable and useful information - do take the advice given!
