as an owner of a couple of waroos, my opinion is:
kite: love the way it flies, i'd give it 8/10 as its not perfect.
in saying that, no bow kite is yet. they are flawed by design.
spectra used for bridle, and attachment points: 5/10. I reckon its low grade crap (on the 06 model anyway). its snapped on both sides of my kite simultaneously causing my kite to go bye bye.
bar: 9/10 its a nice comfy bar, but i wish it had covers from the foam floaty bits to the bar itself. a couple of times slack lines have got caught in the gap, and caused spiral of death. now i know why, and it doesnt happen anymore, but still...
chicken loop/depower strap combo: 3/10. I have seen so many posts on ppls chicken loop snap, mine has also, and ive swapped it for the slingshot chicken loop. i now have faith in the chicken loop again.
anyway, thats my opinion on the waroo. If someone were to ask me if they should buy one, i would say yep, coz the kite is sooo nice to fly. what you save initially coz its a cheaper kite, you will pay for later for all the bits around the kite you will have to buy.
then again, on ALL kites you have to replace bits, so...meh
