I am considering returning mine because of heat.
I didn't experienced pain but it was feeling uncomfortable and scary, and I stopped, maybe out of paranoia, but that shouldn't happen.
I don't understand how HTC could miss such an issue.
I don't know if it could be fixed or not by a firmware update.
I don't know if the product is defective and could be recalled or not.
Since I have 5 days left to return it, I will take no risk and return it.
I also have some issues like it seems I need to turn off WiFi and some wireless devices otherwise screen is garbeled and the connection is lost.
When it works it works fine though, with no latency and a perfect image, but there is that heat problem ...
Also the way it straps to the deluxe audio strap, it breaks comfort.
You feel a discontinuity and a bump on the head.
It can be avoided by not strapping it, but then it put's you even closer to the heat source.
Really I don't get why this issues are there. Some people should be fired ...
