I'm using a Sinewave Revolution after switching bikes to one with a fork that doesn't suit The Plug III I was using previously. I've found the Sinewave to be reliable, though I've not really come up with a position for it that I'm really happy with aesthetically
I've not noticed anything, but I have it mounted on the bars so it's pretty well ventilated. When it's charging a cache battery sat in my stem pack, the battery gets warm in the same way as if you're charging it off a computer
