From my experience with Werter, he is a blunt, honest, and hardworking person. The repairman you need.
He's basically been around the whole computer profession for countless years, and he loves doing it, which can reassure you you're making the right hire. He also loves teaching, so he can provide you information that you really should know. Every day is a good day to learn.
I contacted him because my homemade computer was unresponsive after I attempted to install RAM and an external hard drive. During the repair, he not only fixed that problem, but he improved some hardware organization, as well as software. Basically going above and beyond.
He even followed up to make sure things were running smooth. He cares.
Don't hesitate to seek his services.
