Koo-di Sun and Sleep Travel Cot with Black out Blinds

[Bonfire2010]

Hi - has anyone tried one of these? We are off to Australia in August, stopping in Singapore on the way there and back for a night and I am thinking of getting one of these for my son who will be 20 months by then. Does anyone have any thoughts on them (are they worth buying) and if so, what sort of age does it fit up to as there isn't much guidance on the jojo website? My son isn't that tall (usually fits into 18 month old sizes)so am wondering if it might be OK for him.
