The time has finally come to seriously start the transition to a high-back booster seat for my 6 year old. I'm hoping to score a deal on Prime Day on a high-back to no-back booster seat. He's currently in a Graco Mysize 70, so I don't have any use for a 3-in-1 seat. I've reviewed the recommended lists with CSFTL and Carseat Blog, but was looking for some real world recommendations.

What does anyone have that they like? What do you like about it? Bonus is it has LATCH connectors to keep the seat in place when it's empty (or is this a feature that seems super awesome, but it really unnecessary?).
