I been using Kangaroo for sometime.
No problem sending bigger parcel, their van usually arrive on time (even though their cut off time is 4pm, but the van usually won't come if I call after 3pm).

But sending small item & documents is a nightmare. Their motorcyclist usually doesn't come at all even though I request for pick up in the early morning, no phone call no nothing. Been delay many time for small parcel & documents.
