Is it safe to use styluses with iPads? I know my question sounds stupid but I can't imagine scratching my iPad mini screen!

I have iPad mini (Retina Display) and I'm considering getting Applydea Maglus stylus.

But is it safe to use styluses with iPads? Do they scratch the screens?

Feel free to suggest any stylus!
20€ is a bit steep for a stylus, you can find many on e-bay and such for way less than 5€. They're all generally the same thing: a stick with a rubber dome on one end. The rubber has a similar capacitance to human skin, so it can be sensed by the screen. The rubber dome on the end is squishy and very soft, it will not scratch your screen.
