I've been using the viron in kiteschool for a whole season right now and I really love it. You can give it to anyone and be sure that it's more in the air than in the water. We're using 12 Virons and so far didn't have one broken kite although we tried. the hydra which we had before is complete crap compared to this thing.
perfect relaunch as long there is enough wind (much better than every SLE!)
good for first board starts for light kiters like children
no tangles on the water so far
first starts in highwind use
for normal-weighted riders it needs a lightwindboard an 25knts for going upwind
doesn't really jump at all
it's just something in between trainer and real kite.
