hard to squeeze, hard to fill, hard to get more than a pinch of spice. there is a miniature hole to get salt and peppercorns in the units, they spill everywhere and don't hold much so you're always filling them. The handles are small and hard to hold. You have to squeeze them at least 30 times to get a decent amount of spice out.

Ex Output:
Negative


Ex Input:
A classic story based on history. One of Hypatia's crimes appears to have been ready to provide a hypothesis of a heliocentric universe, long before Copernicus and with a much worse response from the Christian community.

Ex Output:
Positive


Ex Input:
Jenson has updated much information in this quickly-read book. Anyone unfamiliar with his works will find this helpful; veterans of the topic will find new, useful "ammunition." Especially refreshing is the unbiased approach to the Mozart effect studies; a convincing view to show administrators because of its balanced presentation.

Ex Output:

Positive
