Thanks, I found a few on Amazon. Lots of complaints about the heat of course, and many people said it still kept working, but there are a few reports of it locking up or buttons no longer being operational. Some are reporting it would stop working while others saying they actually got notifications on screen about the video not working due to overheating. Good to know!
Also it turns out I got way more hits when searching for "hot" instead of "heat" lol.
Definitely a knock in terms of reliability then. Also functionality concerns aside, even if it works it can get hot enough to start to burn your finger when you touch it which is an issue too.
