I got it and it's not the best quality. You get what you pay for.
It's hard, virtually no padding, and it doesn't sit well rear-facing in our Corsa.
We're keeping it as a spare or for his booster, but I'm glad we didn't pay much for it. I think you could find better quality for just a bit more at Argos...maybe £20-25.
ETA: I've also read that Halfords used to carry them and stopped because of the poor quality and flimsy structure.
