Client Testimonials

“I have been using the Services of Paul O Connor and ONS Limited now for nearly 11 years. In one word ‘superb’ is the best description I can use to describe Paul, his company and the services he offers. He is always there at the end of the phone to offer assistance in any IT matter you may have. His response to a call or query is immediate, something that I know most service providers lack. His product knowledge when it comes to all issues IT and computer related is second to none.”
“We have used the services of ONS for our IT support since April 2012. We found Paul’s maintenance and support to be excellent in every way and our transfer to our new Microsoft Office system was relatively seamless. Paul’s advice when we were looking to upgrade our systems was very practical and always based on what the needs of our users were as opposed to what might save us money. I would not hesitate in recommending them for similar work”
“BCM Business Cost Management has used ONS to support its IT network in Ireland and overseas. We have found ONS to be very technically competent and a provider of top class service. We are happy to recommend Paul and his team to any IT user!”
The Museum has worked with ONS Ltd since I came to Limerick and we have always been struck by the company’s attentiveness to our needs and scale of operation.
Dr Hugh Maguire, The Hunt Museum, Limerick
