Not particularly prone to diseases, although not highly resistant.
Not particularly prone to pests, unlike many early-ripening apples.
Needs to be left on the tree for as long as possible or will be sour and flavourless.
Ripens slightly later than some of "the books" suggest - late August in my (mild) region and probably September in many regions.
Does not appear to be particularly prone to bitter pit, contrary to "the books".
It is my suspicion that M25 rootstock is a better supplier of balanced nutrients than many rootstocks, therefore produces fruit which is less prone to nutrient deficiency, therefore less problems with bitter pit and related disorders.
