I have gained two weeks before the Samsung Galaxy S3 and thus tried three cost input pins, namely: 1. (8/2012 Price: 6.90 + 1.50 P / V) Mumbi Stylus Pen 2. (8/2012 Price: 2.90 + 2.50 P / V) Vau Stylus Plus 3. AmazonBasics Stylus Pen (8/2012 Price: 4.97 + 1.50 P / V) When the two pins of Mumbi and Vau is obvious to one and the same product from the same manufacturer! Except for the color and Mumbi imprint they look exactly the same; the print head is the same and the ballpoint refills also. In using both pins also show no difference. Well suited all three pins for typical applications, tap and wipe ie surfing, text input, images are watch so everything works well. Unfortunately, all three pins but to write to S Memo (notebook) for example only suitable to the print heads are simply too thick and not sharp enough (I tried it with all kinds of pen and brush variants from S Memo.) While you can so write, but it is getting used to and the letters fall quite large and you have to watch that it remains legible. There is also a difference between Mumbi / Vau one hand and the Amazon-Pen on the other hand: Since the print head from the Amazon-Pen a bit softer even than in the other two pens, writing is still working so that a little more difficult. As I said, I am referring to use in a smart phone, not in a tablet! How should I evaluate now? (The pens feature in Mumbi / Vau I do not review, is an average ballpoint pen, really nothing special ...) Since all three sellers have explicitly offered their product in their respective offer text for the Samsung Galaxy S3 is (at least at the time of my purchase) affects as described and the write function with all pins, I can not forgive 5 points. The Vau gets me 4 stars (1 star deduction wg. The write function impaired). The Mumbi receives from me 3 stars (1 star deduction wg. Of impaired writing function + 1 star deduction because it is significantly more expensive than the identical Vau-product). The Amazon gets from me also 3 star: Although he has the worst write function, but it is convenient (and overall it works so well, more or less to write, so that 2 stars would be really unfair ...) I for one am still looking for a stylus with which I can write better. The tip should not be so thick and not too soft ... Gaze mer times ... [This review will be published in all three products.]
