  • Gary Levinson

    Definitely the best service in the area, Lee came to my house and fixed my PC which had been driving me mad for months. He also made my Internet speeds a lot faster at no extra costs and clearly explained to me what the issues were and how he fixed them. The knowledge, experience, attention to detail and price set them high above every other local service I called over the years. 10/10.

  • Maria Lyons

    Fabulous, I cannot praise highly enough!!! Our old desktop finally died & we needed to upload all our old photos, music etc to new pc. Telephoned Lee at Onitek based on recommendations and he was here within the hour. He took our old hard drive away and had uploaded everything to our new pc within 3 hours as well as making sure we had an external drive copy of everything too. Extremely competitive pricing and fabulous customer service.

  • Jo Hertsis

    David and I were very pleased with the help and advice we had from Lee Greenfield. HEe programmed our telephone laptop and tablet,also our heating..

  • Russell Lewis

    I took a punt as Lee was not recommended but I needed a “quick fix” , he is local & was available
    It became obvious to me he not only knew what he was talking about but also spoke in plain non geeky so I understood what he was doing
    Job done with satisfaction at a fair price
    Would most definitely recommend and use again if needs be

    The mini computer is brilliant. I didn't realise it would be so small. It's actually more powerful than my old computer by miles and it's an 8th the size. I'm actually impressed!
