The letters on the black buttons should have been in white to make reading easier. Measurements on the glass container are great features,as compared lacking on my "family 1950's heirloom" Osterizer one speed blender. I like the ice crusher and cleaning buttons but I wish the electrical cord was retrackable after use. Upon first receiving this product, it was so difficult to lift the lid off the glass container.
