I've just received one of these via Sean from builtbysean in Tasmania, Australia and can attest that it is of the usual high EPS quality and fits my brand spankin' T542iXP perfectly and performs as well as expected.
The reduced centre dog length is perfect as mentioned because it doesn't eat into the already short bar length; my thoughts also ran to not straining the plastic mount points on the saw body.
(Picture taken with stupidly wide 16" bar from my 550XP just to see; it would be good for a few cuts but for longer use I'd want .043" or .050" on it.)
