Is investing in a breastfeeding pillow a good idea? Is it really worth it?

I feel it's good for first time mummy or mummy bm for the first time. It helped me a lot because I couldn't get the right posture, leading to lo's and my own frustrations. The mileage is quite short because ur lo outgrown it very soon or as soon as you know how to position ur lo, you don't need it. So it will be good if you borrow from a Friend to try or buy preloved ones. My Brest Friend pillow is recommended by my friend's lactation consultant.
