text: can't charge and use at the same time
  
  The adapter does what it's supposed to and is a nice size. Doesn't feel cheap or flimsy. Biggest drawback is that when the adapter is plugged into the computer, it covers up the other USBC port making it impossible to charge the computer and use the adaptor at the same time. If you intend to use this adaptor to quickly transfer files back and forth then it's no big deal, but if you want to use it to back up your device, or edit files on a hard drive (something that you can't easily unplug w/o losing access to the files) then you should splurge the extra 5 bucks for one with a cord. Otherwise, you can't beat the price
