Protestants are always saying that
but the psg in the Bible about not repeating prayers had to do with people asking God for necessities. Repeating prayers that bring you closer to God through Christ (rosary) is a very good thing.
In that psg, Jesus says that God already knows what you need before you ask. . which applies to both temporal goods and spiritual ones.
I think it is a bit ironic that people are against the repeated prayers of the rosary and yet those of us who pray those prayers are lifted up above the words and don't even think about them after a few minutes because we are in a different kind of ... reality or whatever. After the first few minutes of praying the rosary, I am actually freed from words... It's hard to explain exactly what I am saying.
In any case, I have learned that God prefers we pray a certain way. People asked Jesus how to pray and he gave them (us) the Our Father which is repeated on the rosary many times.
Ther are other things I could say, but I'll leave it there 4 now
