DS (5) was given a kite for his birthday, but it doesn't fly at all well. We'd like to get another one anyway - any recommendations? Don't want to spend a lot/much, and it doesn't need really to do anything other than fly! I think 1 handle probably better than 2 as our 2-hander just seems to crash straight down to earth. Recommendations of something that you've actually managed to make work - with small child holding the string - would be v helpful.
