Pros: good design, price, size
We never used this for sleeping, but had it mostly in the kitchen. Our baby wanted to be in the action all the time, and this was great for having a place to put her while I was slicing onions or doing other non-babywearing-friendly kitchen tasks. Because of the angle she could see out, and it is high enough that she seemed to feel like she was part of things, plus it doesn't take up too much space. It was also easy to move from room to room if we wanted. Now that she's old enough to pull herself out she goes in the highchair instead, but it was priceless for the first six months as a sort of pre-highchair.
