OP author here. My source at the now defunct Datahand company had told me that at the end of the company&#x27;s life they produced very low-quality units. 50% of the units did not function properly, so it&#x27;s <i>possible</i> that was a factor in your trouble learning.<p>More likely though is that you gave up too soon. I know it&#x27;s hard at first but like most things worth doing it takes practice. Maybe I&#x27;m biased by my special situation though.<p>When buying my Datahand I was very lucky. Someone was selling a pair in Sunnyvale for $30. It was in Dvorak (still is) and I had just decided to switch from SublimeText to vim. So for the next three weeks I plowed through using the Datahand (which was easy) on top of learning a new keyboard layout (which was hard) and all the vim movement&#x2F;editing commands (which was annoying). It was a big chunk of effort. The hardest part by far was __not cheating and switching back to my normal habits when the going got tough__. If you already know how to accomplish a task and you&#x27;re trying to learn a new method - it&#x27;s very, very hard not to fall back to your proven method under the pressure of frustration. I fought that pressure many times over those three weeks but it&#x27;s been one of the easiest and most rewarding investments. There&#x27;s always time to save time, and their&#x27;s always time for your health.
