This isn't from a new review, so many of you may have already read it, but it is absolutely hilarious!
"The M80Tis have three large ports -- one in front and two in back. These are corrugated, apparently to increase surface area, and are flared at each end to discourage chuffing. The appearance is somewhat disconcerting, as, to me at least,
they resemble the port that one might find on the backside of a large gorilla. Things got even more disturbing as I watched my cat pulling out stuffing, reaching in up to his armpit like a jungle veterinarian. But the grille hides the front port, so odds are you won’t lose sleep over it."
