Just this morning I went and picked up my friends 'Peg-pérego' brand car capsule that she's giving us. It's one of the 2 part systems where you strap the base into the car and then latch the top part in. The base unit itself is sitting solid as a rock. It has a knob on it so that once you strap in the base unit, you turn the knob and the base jacks up a bit to make it an extra tight fit. The seatbelt holding it in place is as tight as a piano string!

The top then clicks in and baby is safe and snug.

OK so I do appreciate that the pro's might be able to do a better job than someone who hasn't read the instalation instructions but for our seat at least I didn't find it hard at all and I'm totally satisfied with how secure it is.
