The market for nursing sports bras, particularly for larger busts, is incredibly limited from what I have seen, but I expected these to be better given the hype on social media (including from pregnancy fitness influencers) and the high price. However, they are just OK. They are quite ill-fitting, feel like a bikini top, and don't offer great support (although to be fair they are marketed as only medium support). I realise nursing sports bras is a niche market segment because breastfeeding is typically only carried out for a snapshot of time and not all people nursing will require a sports bra, but the broad fitting - especially for larger busts - is never going to work.
Positives are that they are relatively comfortable, the feeding element works well, and they look nice (the blue is a really nice colour).
