These are cheap, addictive and great fun. On a good day they will fly for quite a while. Find a good open site or you risk losing it quickly. (And get a stronger elastic band for launching - well worth it for the added height and flight time attained.) If someone else wants a go - tell them to buy their own! :)
My son had one of these before and unfortunately his friend lost it in the field hedgerow! But it was so good we got him another for Christmas - much to his delight. Make sure you have plenty of space as we have had to rescue it from very high up in a tree, and you need to keep an eye on where it lands. It does exactly what it's supposed to, and goes VERY high. Very durable too. My son loves it, just got to make sure he holds on to it this time! A Winner!
