I have the sns unity capsule and profile stroller as it clicks onto that. It has been great, my dd is still in it at 18.5months, though she not a big girls she is small for age, 76cm and 9.5 kilos. I am actually not looking forward to changing seats as it becomes squish when we put the next seat in. Plus if I put her carseat reward dh can't drive the car. The unity fits well in my car and i love that it can go on the stroller etc.
