Great service, very professional and knowledgeable.
Kept in touch constantly throughout a complicated back up and recovery process & complete reinstall of the system. Saved all my files too! Will recommend D7Logic to my friends and family! Thank you again!

Deran was incredibly responsive on WhatsApp, generous with his time, and flexible regarding working time. I am not good with tech and had lots of silly questions which he guided me through for no extra charge. He really went the extra mile, and fixed my laptop the same evening I dropped it off! Highly recommend D7Logic!

My computer had gone crazy. The mouse had become non-functional. Documents were moving all over the screen and a large loop kept appearing as well as the on screen keyboard. It was mayhem. I contacted D7Logic at about 8pm. By 9pm they wrote back and advised me what to do. By 10 the problem was solved. Absolutely amazing service. Malcolm

I took my laptop to Deran as it was not working properly. Deran completely revamped it and he installed windows 10.i was expecting to leave the laptop until the next day but Deran was absolutely brilliant and i got my laptop back a couple of hours later. The cost was very good and the service was outstanding I would highly recommend d7 logic .

Fantastic service by Deran – asked for a job completing on a make and model of PC which Deran was unfamiliar with and which is not sold in the UK, yet he managed to complete the job and deliver my computer back to me within less than 12h of my dropping it off. Knowledgeable, easy to contact and most of all, very fast!

The guy is a genius. He revamped my 10 year old PC and recovered my data when I thought all was lost. Now it is working like a brand new computer. I am so grateful for his expertise He can pinpoint exactly what was wrong with the computer and he stayed up all night to repair it. I am forever thankful and I certainly recommend his service; it is the best.
