we've got one. here are the pros and cons (as they pertain to me and my DD):
pro:
1) super comfy, and ergonomically correct (passes strict german standards for this... anyone who's sat in a german engineered seat knows what i mean)
2) SIP is very prominent, and is adjustible to the child's height
3) EPS foam
4) fabric is high quality and super plush, even the seat sides are covered, unlike most seats where the sides of the carseat are exposed plastic
5) installs rock solid (may not apply to everyone, but in my car it is very easy to get a rock solid install in 30 seconds)
6) base is nice and smooth on bottom, no sharp spikes like on some cosco seats
7) very sturdy construction
8) becomes a BPB good for 80 lbs and 59"
9) very easy to tighten harness
10) recline mode (not used to recline, really, but to get the seat to fit better in some cars)
11) SIP functions as a head rest for our daughter, who sleeps with her head against one side... her head never flops!
12) relatively narrow, so fits in small cars well, and should work well in situations where you need three seats in a row.
13) nice IMMI-made LATCH connectors
cons:
1) harnesses only to 40 lbs
2) adjusting harness slot position is cumbersome and confusing, must also adjust headwing SIP height separately
3) toddler pillow slips out of place easily (optional anyway)
4) crotch pad slips off buckle easily (optional anyway)
5) harness straps tend to twist at the buckle (common with all seats using the newer, thinner IMMI-made straps)
6) some kids don't like the SIP... they find it obstructs their view or makes them feel confined
overall we love it, and my DD nevery complains about discomfort, even after hours at a time. we will most definitely be buying the new recaro for our second daughter.
