We have owned several stylus' over the years. The major problem is the soft rubber tip. It deteriorates over a short period of time. There must be a better more durable tip material for this application. Or lower the price. I would recommend this product for short term use say 3-4 months.
With electronics you are never done buying the next gadget. But the stylus has come in handy and does keep the screen cleaner. I purchased two because like reading glasses they always seem to be in the wrong room. Two gives you a chance of finding one when and where you need it.
