Customer Testimonials

  • "Another good speedy & efficient service from Killer-Byte. Highly recommended."

    - Roy, Sheffield

  • "Just a quick e-mail to say how delighted we are with the dell laptop you sold us and of the service we received just over a week ago. You can be assured if we are in need of other products we will come to KILLER-BYTE LTD."

    - Janet and Brian, Dronfield

  • "In January 2014, just before I was 67, I decided to buy, for the first time, a laptop and printer. I knew absolutely nothing about computers but was ready for a challenge. My first problem was connecting the laptop and printer. A friend gave me Killer Byte's phone number and in a short time I was sorted out. I have called on them several times in the last year and have always been impressed by the expertise and efficiency of all the staff. I have no hesitation in recommending them."

    - Josephine, Halfway, Sheffield

  • "I just wanted to say 'thank you' to you and your team for organising a site visit so quickly to rectify the problem I was experiencing with my laptop. Andrew was extremely helpful as always. He sorted the matter out in an hour and left with the system firing on all cylinders! So, as always, you and your team never fail to deliver anything other than an exceptional service."

    - Jayne, Wincobank, Sheffield
