I keep reading how everyone loves this seat and I know baby bargains recommended it. Does anyone have any actual feedback good or bad? Maybe it was just me, but when I tried it out in the store with my toddler I had a dickens of a time trying to adjust the belt using that knob. THat is the big thing that turned me off to it. Is it supposed to be that hard ? (I was pushing in and turning). ALot of people seem to really like it so I wonder if it was me or this particular seat?

Is there any "downsides" to this chair?

Thanks!
