Love the straight-down action of the frets of this (vs the wobbly buttons on the standard RB plastic guitars) and the clicky strum bar (vs the silent squishy one on standard). I agree w/ aem, though: the strumbar on this is more clicky than on a regular GH guitar.
That said, as soon as I found a deal on the Logitech GH wooden guitar, I wound up going right back to that one because I generally prefer the shorter neck length and button layout of GH controllers. (But man, this thing is way too orange.) The strum bar is quieter than the standard (a duller thud rather than a "click").
Am I the only one that hates that RB controllers require three batteries instead of two? It makes recharging batteries more trouble than it ought to be since I have to divide my four batteries into two groups A) a pair that always gets charged and B) a pair where I alternate which of the two gets to be the "third wheel."
