Splitting occurred pretty rapidly with mine also -- I believe them when they say that this LE was made with an exceptional quality boar hair.
Apart from that I noticed that the black stain they used for the 'fake two-tone' effect bleeds pretty badly. I can still see traces of it in the lather I squeeze out of the knot when test lathering. I won't consider the brush fully broken in until the bleeding has stopped.
Overall I'd have to say that, while not being the greatest fan of boar brushes, this is an exceptionally good brush. I could probably get by with it as my only brush.
