I've got an AM-FM radio with an auxillary input that's still going strong since around 2007. How'd you find the owning group / what products they're rebranding?

The grundig site has a Beko UK security certificate! I'm pretty sure the Turkish group renamed some of their old Beko electronic divisions, including radio, to Grundig after the takeover. Not sure about appliances as Beko already had decent presence at the cheap end of the market, so Grundig was maybe a chance for them to try to move upmarket a bit.

Takeover was around 2007 so you could possibly have one of the last "proper" ones. No idea which particular products or if any old Grundig products survived a while longer. What shows up in search now is nothing like the type or quality I'd have once expected of the brand.

I remember selling Beko products back in my electrical retail days (around 2007 in fact). FWIW they were cheap and cheerful but not absolutely terrible quality at the time. Probably a step up from most of the supermarket own brands. Not sure how the company has progressed since then.
