The express I got was listed as refurbished and was only $25.
I bought a Roku Express directly from Roku as a replacement for an XD model recently and I have found that this model also runs very hot when plugged in. I have had to resort to unplugging it when it is not being used to keep it from getting too hot but this is not an ideal way to deal with the issue. I believe that Roku should fix this poor design by replacing the parts causing the overheating or by adding a better heat sink and cooling fins to dissipate the excess heat properly. I am just hoping that this isn't presenting a potential fire hazard to Roku users. If this unit were to "burst into flame" as it self destructs, I suspect that Roku would be subject to any number of law suits from customers.
