The last two times, in summer and fall of 2013 I got units delivered, the (over several weeks) gave even after long use a strong acrid smell of itself. And these nasty plastic stench I would not really have them around and near my smoothie. Above all, I reckon that with me sometime this oil would run out, as others have described here.
Mir is the risk here just too high, because as others write may leak oil, without you knowing it.
If Philips would get times in the handle of the blender would absolutely great for the price.
Unfortunately, I can think of no alternative.
