Mr Edison gives 6 reasons why his Phonograph is superior

Reading the Edison Phonograph Monthly ,from july 1913, I noticed a statement of Mr. Edison giving 6 reasons why the Edison phonograph is superior :
-Because it gives just the right volume of sound--is not too loud;neither is it harsh nor metallic
-Because it plays the Blue Amberol--the sweet-toned four minute record which is indestructable
-Because being supplied with the new Diamond Point reproducer, its contact points never needs changing
-Because the new Diaphragm (the result of thousands of experiments) re-
produces the colrtones or overtones,heretpfore impractical
-Because it is the only type on which records can be made at home
-Because, being made under Mr. Edison's supervision, it embodies technical excellence'es that exhaustive experiments have found desirable

What do you think ---we are in 1913!-- is at that time a true benefit?
