Ive been with Gilt since the beginning, pre-app, and the first couple of versions of the app were rough. But the improvements are really remarkable. I particularly like the different ways that you can find products - either through search, through categories, or through their own editorial concepts (e.g. Summer nights).
Its a little frustrating, the five minute hold in the cart, so you might sometimes have to write down the items you want, then quickly pick them all and add to the cart. But this is Gilt - no holding in a cart, because the number of items is limited. All in all, a good experience. Ill be back for more.
