I find it to be completely reliable. It handles transient loss of wifi and loss of connectivity to their cloud, doing retries and so forth. I have had 1 issue in my 2+ years of use where the device rebooted while I was in the middle of writing something, and when it came back, only my last couple of seconds of writing gesture were lost. I don't think about it from a reliability perspective. I have been pushing data to mine as well, with a local amalgam that de-drms kindle books, convert to pdf, push to remarkable cloud, which is then retrieved by my device. Have done > 100 books, all good. Really great device. Would contribute equity to them were such an option available.
