We have bought Daisy rolling case for our 4 yo daughter to take on holiday to Russia, she absolutely adored it, played with it all time before and on holiday and I have to hide it now, as it became her favorite toy! This was a brilliant buy. We traveled with 2 transits and this tiring for adult not to mention 4 yo, this case was our saver, because she just could sit on it happily and I pushed her with a speed I needed to go to catch another plain, otherwise she would needed to run to keep up with us. The case fits perfectly under the plane sit in front of you (we had tried it on EasyJet, Rianair, Aeroflot, Transaero as we've been in Spain and Crete since) so we had all her toys and books next to us. Recommend to anyone. Well build and fun!
