Q: 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.

A: Negative

Q: I am using this pillow now and about to enter my second trimester. I find the pillow to be comfortable and useful in training myself to sleep on my side. I actually find the pillow most comfortable upside down (with the connected piece at my feet). This allows me to use the side bolsters, elevate my feet, AND use my own pillow.

A:
Positive
