The Grundig I've had for less than 6 months has broken down and I can't get anyone to fix it because the service agent (United Electrical and Bush in Australia) does not answer e-mails or follow-up calls. It has been 4 days now and three attempts to get my warranty honoured.
This follows 5 calls and two e-mails (unanswered) when I first bought the TV last November to get the wall mounting right (it now hangs on the wall with half the stand still attached, because no one could or would tell me how to remove it- not a good look).
Therefore, my rating is that not only is the Grundig product of poor and unreliable quality but customer after-sales services is non-existent. Apparently they do not think it necessary to honour warranties. Don't buy this brand.
