Booster seat advice?

Je
I am considering purchasing this booster seat for my four year old. He weighs 45 lbs and is still in a convertible car seat. 
If anyone has the Graco Affix and can provide feedback on it I would appreciate it. Or if you can recommend a better booster that would also be helpful. 
Thank you and have a nice day! 😊
