We have one, it is our travel seat. I use it in airplanes because it is narrow and light.

It needs a pool noodle or towel when installed rearfacing and iirc, the limit isn't that high, weight wise.

We have the pink one in Dan's car, because it was cheap and she doesn't ride in his car often. I was expecting it to be crummy since it was cheap, but it's actually really nice. I thought it was pretty easy to put in. We had to use a rolled towel to get it to the right angle, but we've had to do the same for her infant seat & the more expensive convertible in my car. I have no complaints about it!
