Centrum Serwisowe MIK

It’s an excellent service center for Apple devices.
They’ve fixed Mac for free while another center requested $ 1000 for the same operation. Well, it was a kind of a problem Apple should pay for, so it should be free, it’s just that other services do not check all possible warranty cases.
They transport all stuff to Radom where they have a huge center for fixing stuff. The estimate for repair was around 2 weeks, but actually it was finished several days faster. It’s possible to track the state of the reparation on their website. When it’s finished, you are notified by a phone call and have to come in person to get your device. It’s nice as I do not really trust in postal service reliability. In general, I’d highly recommend this place for any troubles with computers and other devices.
