It is convenient and provides many of the features it promises. I didn't like that it doesn't latch onto the Mac Mini; it's just like a stand, resulting in the Mac Mini moving every time you touch it.

Absolutely necessary if you do serious work with your mac. Read the reviews elsewhere and you'll understand. Couldn't be happier.

After about a year of using this particular hub - adapter, I can say that it is stable, does not lose connection, nor does it have any significant drop in the speeds at which it transfers data.

Very nice base, no issues so far. I also installed an M2 2TB as an extra system drive and the speeds it achieves in transfers are at least as much as the manufacturer claims. For everyday normal use and file transfers, the times are very low. Inside, it had a pad for heat dissipation to be placed on top of the M2. The USB ports work well as does the card reader. Really very nice and practical base that offers many extra ports and very good speeds at a reasonable price.
