For a Beastmaster it is excellent.
Not so much for the speed increase, but for the rest of it. It does not stack with Carrot on a Stick, Mithril Spurs or Riding Crop. But it does save you the effort of getting any of those things. Keep that trinket spot for something else, the enchant slot on your boots for +agi/runspeed.
But in the end it is up to you. Do you want that talent or not?
