about the Pi Hut itself, just perfect. web site easy to use and order things. received everything without problem. for the NanoSound ONE Raspberry Pi 4 Case (with a pi 4), it's something else. you should add a few warnings for this product: - do not forget to have a very small micro-hdmi to hdmi adapter because sound cinch connector is very close to the hdmi one. - and after that, no way to have a display on my acer dm431k 4k screen. it seems there are some hdmi problems the the pi4. I spent lot of time modifying the config.txt file. but no success. it seems there is a signal level problem with the p4 and I didn't find a way to make it work (either 4k, full hd or hd ready). and it works perfectly on another acer full hd screen.
