Are you sure that's the display coming out? Isn't that just the invisible plastic cover in front of the display?
I had the same 'problem' and just had to put glue behind it.
But yes I have to admit I'm also kind of disappointed, my EMI filter on the aquaero PCB was maybe 1mm too high, and if I had put too much pressure on the screws when attaching the passive cooler I would have damaged it, in fact I did a little so I had to bend the component, and to make sure it wouldnt get damaged I even cut a hole on the side of the holder so the component gets as much space as possible.
And yesterday problem with flow meter, when paying 60€ for something like that you don't expect these kind of problems.
I guess it's just bad luck, but if I will buy something from them next time and get some problems again it would certainly make me think twice, like I said in another thread they are destroying my myth about german precision and tendency to perfection
