Cantaloop’s Adjustable Drop Cup Feeding/Nursing Bra is comfortable to wear, doesn't dig in anywhere and is breathable in hot weather. Breast pads fit easily into the bra and the panels can be open/close with one hand (although it takes a bit of practice). The drop cup clasps are very secure and feel reliable. It's adjustable too, so copes with fluctuating sizes.
The bra supports breastfeeding when out and about with little ones but as breasts fill up, the circle cut-out around the nipple can become quite tight (even with the correctly-sized bra), which could lead to milk blockages. It’s also ‘high-cut’ and thus visible under low-cut tops.
Overall, a quality product that is good value for money.
