I actually had this a number of years ago but forgot to post a review about it.No heat issue even for switch on for 14-15 hours every day.
It is pretty rare to have all 3 technologies in 1 router device - a modem, a switch, and wireless access point. It was a bit power hungry but at least it meant less components to deal with which means more convenient for space constraints and aesthetics.
Wireless feature is quite good with well range.The does of course mean that if one part of it breaks, you will likely have to replace the entire thing.
