we have the capsule that goes with the strider dlx. it didn't have any reviews on choice when we chose to get it as it was pretty much brand new, but given it was a safe n sound brand, and the others from britax had a good reviews so i was confident in getting it. E is pretty much average in weight and stuff, and will "graduate" to her meridian next weekend (i think) based on her weight. the only thing i'm disappointed in is the weight range - it only goes to 9kg - one of the others (unity i think) goes to 12kg - but that is the same rearward range as the meridian so it's not like we get any longer rearward (does that make sense?)
