I have an original rev, a Supersonic and very recently purchased a Revolution Blast.Some of these kites are over 23 years old and they're still.in fairly good shape.These kites I find are challenging to fly ( especially the Blast). The packaging and fit and finish of the kites is remarkably good. Materials used are top notch.
I have watched Revolution knock offs fly, and I think they are not even half as good as the Rev.
My most recent purchase,the Blast is a handful and will require hours and hours of fun to master all the skills.
Cheers Gavin
