What our clients think:

I recently had my old laptop repaired by Mr. Kantermann, and he provides an excellent service. If there are any uncertainties, he calls in advance to clarify whether the repair should be carried out and is always available for any questions. In my experience, the few negative reviews are unjustified and absolutely incomprehensible! A fast and consistently satisfactory service is offered at very good prices. I will gladly return if needed & will also recommend your repair service to friends.

Best regards & continued success! =)

Hello, I recently had an experience with A&O Computer Service, and I must say that I am very satisfied. It was a Sunday when I was writing a report for work on my computer, and unfortunately, the computer suddenly turned off and wouldn’t turn back on. I called Mr. Kantermann, and despite it being a Sunday, he said he would come soon. In about 20 minutes, he was at my place, checked the computer, and told me to come back in about two hours. I did as he said, and I was surprised at how quickly everything was fixed. Now, if anything happens, I know exactly who to contact. Many thanks to you, and I highly recommend this service because it is fast, reliable, and solved my problem!!!

Imagine: it’s Friday evening.. your Harddisk is no longer responding.. Monday morning 10:00 a Job interview via Teams is sheduled, with an Assessment, for which you will be given a case to resolve. And present it by Powerpoint. After a sleepness night trying to fix: a phonecall and a visit on Saturday morning to A & O did the job. Saturday evening a new harddisc with all my data was installed. Being faster and running more smoothly than ever.. By the way : I did get to Job! Thanks a million!!
