Thanks so much! After days of researching, I ended up getting it at BRU for the sale price. I did install it in my car and I absolutely love it. There is plenty of room for a passenger to sit up front, which means there's plenty of room to extend the head rest on the MySize as he grows, since I'm planning to RF until at least 4.
There is a bit of wiggle room when installing the seat to get a more upright recline. Pull the restraint out from the back of the car's seat - just a little, and push down on the seat of the restraint and then tighten the latch (or seat belt if that's what you're using). I was able to get it more upright like that and the ball is still in the blue. I'm not sure if you have leather or cloth seats, but I have leather and I had to push down quite a bit.
