DS liked to sit in it for short periods of time, starting at about 5 months old. It was also a useful seat for picnic lunches (on the ground, of course) until he outgrew it at about 10 months. Definitely not a necessity and not something you need to buy when you're getting ready for a newborn. We borrowed the Bumbo with DS, but we'll probably buy one when this new baby gets old enough to use it.
I've used it with both my boys quite a bit and they both like it. They both were long and skinny when they used it and it seemed to prop them up fine. I could see where it would be uncomfy for a bigger baby. I did see this in Walmart and it seems like it would work better for bigger babies.
I know some kids love them, DD didn't so much for the most part. It was most useful for us while I was getting ready in the am - Id put her on the floor in the bumbo and give her some things to play with while I did my hair and make up. Im glad we had it, and kept it for LO2.
I never got one since I couldn't justify paying $50 for a plastic seat that would only last a couple of months. Plus my son's day care had one so he could use it there.

I had the older version of this seat.
