I think that is the one we have for Jack and I like it. He is still able to use the 5 point harness at 4yrs and should be able to use it for quite some time.
The only downside is that I can't use it in Mum's car. The seatbelt goes around/over the little armrests on the seat, Mum's seatbelt has a safety mechanism in it that means that once seatbelt is done up and tightens it locks and won't extend out until after it has retracted fully (clear as mud??!

). Anyway it means that you can't pull the seatbelt out to go back over the seat arms when you want to take the booster out. Only a worry if your seatbelts are like my Mum's
