My concern with MTD in general is its overall mediocre quality. Now I know some guys who have had good luck with MTD splitters, and others who have had terrible luck. I just don't have a great deal of confidence in their products or in the ability of the point of purchase to provide any support or guidance in the event of troubles now or down the road.
Their products are targeted to a particular market and in all honesty usually do a decent enough job for that market. My father purchased an MTD 8hp snowblower about 7 years ago and it is still working fine. The sheetmetal is flexible as heck and had to be hammered back into shape after hitting cracks in the pavement, and many of the smaller parts rusted and needed to be replaced, but it does work. I shudder to think what a new machine built like my restored 1967 JD 724 snowblower would cost today, but suspect it would run a good bit more than dad's MTD machine. So at its pricepoint MTD does a decent enough job for many users.
Like TroyBilt, Homelite, Poulan, and McCulloch, the quality of products in the MTD family has been progressively decreased while the remaining goodwill vested in the brand or mark is exploited for all it's worth. For that reason alone, as a principled action, I avoid their products even when a product happens to actually be usable for a particular task.
If this little 123cc splitter proves to be a workable, solid unit, then that's great. I just don't have a lot of confidence in the brand or the businesses that sell it.
