I concur with the others. Definitely not a good seat.
If money is an issue I'd recommend a Joie juva (about £40) as the infant seat and that will give yourself time to save up for the next stage seat.
Another benefit of getting a dedicated infant seat is that you can see what centile your baby is on. A child high on either the weight or height centile will need a carseat which harnesses to 25kg. The majority only harness to 18kg.
