Up to the quality of the Mac itself. Same finish, looks like it came with it. And amazingly, it DOES run MUCH cooler while in this mount! That's good for the internals to last longer with less heat stress. That alone would make it worth using! While I see one reviewer mention that the silicone gasket could be glued down, it's not necessary, as it holds very well and secure as it is. While just the tips of the clear feet make contact, they also grab the whole unit without any slide risk seen.
Well thought out, I'm impressed, and happy to have recovered some shelf space, with class! Small LOGO on one side of unit is easily turned to the back, so you don't have to look at "more" marketing, unless you want to.
Overall, the best and most simple solution I've seen. Definitely worth buying to save space, and keep it running cooler!
Thanks NuTech, brilliant and functional design!
