We are very grateful to Vlad for his excellent service repairing our personal laptop. Our laptop suddenly got infected with adware popping up everywhere on our computer screen and we needed a speedy and reliable service to get it fixed asap. We came across … More Dr IT Services and were lucky enough to be able to book Vlad on the same day. He very speedily diagnosed and fixed our laptop on the same day, and for a very reasonable price. We cannot recommend Vlad enough for his computer repair services!

I contacted Vlad after my son fried my laptop by using his powerful charger in my less powerful laptop. I was very anxious.
He was very responsive when I made initial contact and I was above to drop my laptop off that morning.
The service was supremely … More professional and very quick. I even brought my son's laptop (which was broken and that is why he was using mine) to be fixed too.
I was given clear prices and expectations for how long the repairs would take. Both repairs were completed very quicker and exceeded expectations.
I would highly recommend Vlad.

Great laptop repair! Fixed my HP envy screen. I was so worried about how much it would cost but Vlad gave a very low cost price and did an excellent job. Looks good as new.

Highly recommend.
I contacted Vlad as my laptop wasn’t working. (Would not power up). I dropped it off to him in the morning. Then later that day he was able to diagnose the fault and put forward a plan to resolve.
Unfortunately it was not economical … More to repair, but he was able to source the perfect replacement for my budget. Which I couldn't be more happy with. For a small fee he was able to transfer all my data over to the new device.
All turned around in a few days.
The service was fast, friendly and had great communication. I would highly recommend to anybody who needs their devices repairing.
Thanks Vlad.
