What unfortunately is not working: installed my 30-inch Cinema HD Display. :(
The foot of the monitor is approximately 2cm too wide. As stated in the article description was "for all Thunderbolt + Cinema Displays" I assumed that even fits in my. Since I have are the monitor now on the HiRise and so far also fits I kept it and the extra storage space is now used for external hard drives (2x2.5 inches). Also okay.
Inexpensive is definitely something else, but it was always like that. Who wants to buy some style just needs to dig deeper into their pockets.
