I use them on large T.Vs in conference rooms and network them through Wi-Fi.  Haven’t had a problem with any of them, they stay powered on almost always.  Memory is find but I don’t do heavy computing, just Videons and accessing the internet and shared drive.  I can Velcro them to the Tav and never a problem.Light weight, don’t get hot and,reliable.  You can upgrade them but I don’t need to.  Will continue to buy.
