Unfortunately, I agree with this. I was an early backer on the mini, and got it with the aluminium case. While the case looked great, it mechanically interfered with the antennae, meaning they didn't actually make a connection. Their support taught me how to screw in an antenna, ignoring the actual problem, before deciding my issue was too hard and ignoring me. I got eventually got in some antennae from Ossmann, but when other hardware/software issues cropped up, my enthusiasm for the device had already waned too much to want to put in effort. I got some basic things working eventually, but never outperformed cheaper devices.
