I had just bought an iPhone 5S - my first smartphone - but was having a lot of trouble with typing, making loads of mistakes and having to go back over the notes etc to correct them. I have quite small hands and fingers so I cannot imagine how others, especially men, with larger fingers manage. Then a friend suggested a stylus and I went looking. I found quite a few on amazon and decided on these which seemed a very good buy, since other reviewers had complained that this type (with the attachment which fits in the audio socket) often broke and the larger pack would help with this. I suppose it depends on how one carries them around, but so far, I have not had any problems and, more importantly, I make far fewer typing mistakes! Excellent value!
