I picked this up in a sale via mighty ape so I would say it has been worth what I spent on it and really I bought it just to see how it might hold up against the more expensive options such as Wacom and Apple styluses. Unfortunately, it has no real comparison, it is certainly more accurate and fun to use than many standard iPad pens but the slight contact delay and lack of real precision make it something that is only really useful for fun rough sketches and perhaps writing.
