Task: Sentiment Analysis
Input (English): I started using NuStevia several years ago.  Back then I had to purchase it from a health food store.  Thanks to Amazon I can now order and have it within a few days.  I never run out!  As for the product, it's the best.  I've tried several Stevia products but they have an after taste.  Not with NuStevia.  Please try if you haven't.
Output (English): 5
