"Yesterday in the afternoon I've plugged charging for the first time after update, and I've noticed that charger is very, VERY HOT, which has no place before update. Charger was so hot, that I've decided to unplug and not leave it for night charging. I'm charging now, but it's still hot as hell."

"My charger gets dangerously hot but only while its charging. Once both the dock and the tablet reach near 100% it cools down significantly."

"Well my wife had her tf101 melt yesterday, the charger was too hot to unplug from the wall and the cable at the tablet end looks like this... That enough proof, not saying the OP was not a liar, but mine could have done more damage with the heat that was coming out the plug end. Lucky she was home when it happened." (with photos as proof)

"Well if we are talking about great charging experiences today I plugged in my EEE Pad charger and was greeted with huge spark. Let it charge and no fires have started thankfully."

"The same happened to me, I was plugging out the usb from the charger and the usb box came out o.O

I knew this was going to happen someday because it was always extremely hot right from the first time I charged my tf101."

"My first tf700 that I got delivered on the first day of release had a bad charger. First time I plugged it in, then plugged in the USB cable then plugged the cable into the tablet. It immediately arced sparked and smoke came out of the charger. It visibly had a smoke mark and was too hot to touch when I snatched it out of the wall. Returned it all. "

"The Asus wall wart that came with the Prime failed, and I would not put much trust in using the second one that I have (the Asus wall wart that came with the Infinity), and I will simply not use it."

"I had a similar thing but far less demonstrative, happen to my Asus charger for our Prime 201. The unit was only about two months old at the time, and the charger did indeed get hot (very hot, you would not want to hold it in your hand for over a couple of seconds) when charging the keyboard dock and tablet. One day it just quit."

Is that enough proof for you? Multiple references to the charger becoming too hot to touch and/or melting, and three of them include photographic evidence.

And speaking personally, I own four of these chargers currently, one of them regularly locks up and stops charging until you let it sit for a few hours, one of them overheats badly to where it is uncomfortable to touch, and one of them the plastic clip that holds the plug in place snapped off the very first time I removed the plug and it's now unusable. Only one of the four is still properly serviceable.
