Received it very quickly that was the first great thing. This works on like every finger capacitative touch. I have used it on a couple tablets, iphone, ipod, even my macbook pro touch pad!
It does what it says it does, and at this cheap it cant really get any better!
Sliding is sometimes a bit off, mostly just due to the rubber tip and not pushing hard enough. Although you dont have to push super card, it does work!
As with the rubber tip, I am not sure if I would want to use anything other then a rubber tip, I guess the only thing I might keep in mind is its durability for dragging/sliding as it does put some strain on the tip. however it seems to be well built.
Definitely no qualms, definitely recommend, conclusion: wouldn't be super useful on games and drawing apps, as the games are really no designed for a stylus, and also it is rubber gripped and the finger just slides better.
