Very happy with this purchase! The kite is easy to assemble and get in the air. I have never used a round spool for stringing and it is very easy to unwind and wind the string, especially for small hands. My 4 year old had no problem holding it even in fairly strong winds (he's pretty strong for his age). There are lots of thoughtful little things like the line clip, the elastic tip cap and the fact that the assembly instructions are printed. on a pouch that also holds the spool very well and has a clip for hanging. We have tried many kites over the years and none have been as intricately designed as this one.
