I ordered per the size chart and they fit absolutely amazing! I wasn't expecting an online bra to fit this well so I am definitely surprised! I used to spend hours at store after store, so once I found one I bought those and only those. These changed the game! Hooray for not doing laundry every 3 days!

Ex Output:
positive


Ex Input:
4 times now I tried to order this DVD--twice from elsewhere, twice now via Amazon, and ALL times I was sent Blu-ray even though I ordered DVD! The DVD is listed separately from blu-ray: the boxes are different, so I zoomed the photo claiming the "DVD" format, ordered clearly under the "DVD", and under the lower DVD pricing, as Blu-rays are sold at a higher price. Each time I am sent the Blu-ray!!!! I am so frustrated at this terrible advertising! Why is the photo/descrption/price for DVD offered online if only Blu-ray is available? Blu-ray doe NOT work on my DVD player and just want what is clearly marked as offered!

Ex Output:
negative


Ex Input:
we have very spoiled dog. they eat this canned food on top of natures recipe dry easy digest. my pitty bull has IBS and is able to eat this with no problems. They score well on their Vet visits, their coats are shiny, eyes are clear, and blood values are good whenever they are done. I can't think of any down side to this food.

Ex Output:

positive
