This bra is a godsend for busty women with shoulder issues.  I have tried on a dozen bras, mostly back-closure because front-close bras in my size (36G (US)) apparently don't exist... none fitting as nicely as this one.  It provides excellent shaping and support, lifts/separating beautifully and keeps the girls in place without requiring constant adjustment (this is sort of a plunge style, rather than full-coverage, so I expected some adjusting required).  There is a plastic friction strip sewn into the upper hem that assists in keeping the girls exactly how you positioned them initially, and surprisingly, it works really well without the wearer being able to feel it.  The satiny material is extremely soft and comfortable, and very nice construction for the price.  I have worn it for a week straight without taking it off (at 36G I have to wear a bra to sleep.... you smaller chested ladies out there, count your blessings!) and it hardly caused any indentations at all, which in my experience is miraculous.  The padded shoulder straps are about 3/4" wide and are very, very comfortable without being bulky.  The band is nice and wide to minimize back roll appearance, a huge bonus.  I must say I was apprehensive about buying a front-closure bra in 36G because the physics doesn't warrant optimism, but frankly the construction of the bra overall along with the sturdy clasp mechanism seems like it should hold up.

Two things to note about the fit of the band here:  front closure bands are not adjustable, and I wear a 36 band on the closest hook set (a little bigger than the farthest setting on a 34 band) and this particular band in a 36G fit me perfectly.

I will update after a few months of wear on the durability.

Update:  I bought 2 of these and at 6 weeks of almost daily use, the white one's clasp broke.  The red one is still going strong at 9 weeks.  Just be gentle with the clasp and make sure you are wearing the correct band size - I think my advancing pregnancy (i.e., expanding ribcage) combined with rough handling trying to adjust it while wearing (again, due to expanding boobs and ribcage... pregnancy sucks) was too much for the clasp, but most people won't have this issue.  I would still recommend this bra, just with the caveat to be gentle with the clasp.  I just bought another one in the next band size up.
