I'm not sure about "fair" but as a practical measure I think it's counter productive. I've never asked for a refund but every single purchase I've made has been partly because I could rationalize that I could return the app if I really didn't like it. With only 15 minutes to try it that logic won't work for me any more - I think I'll be doing way less purchases. I don't understand why Google wouldn't just drop it down to an hour which would accomplish the same (stated) purpose but be a lot more reasonable.
