If you like neither Hub + nor Voltus, this USB-C hub from Satechi should solve the problem of missing ports on the new MacBook.
Available in three silver, space gray and gold notebook colors, the hub offers three standard USB 3.0 ports, one slot for SD cards and another for microSD cards.
In my opinion, one of the USB ports could have been kept in Type-C format (because, with the hub plugged in, it wouldn't d charge the MacBook); but it was cool. The biggest blame in this case of Apple, even, that should have put a second USB-C port on the other side of the Mac.
The accessory goes for $ 35 in the United States.
