• Be objective and truthful. Tell us how you really feel. Good product reviews include not only whether you liked or disliked an item, but also why.
• Be detailed. Don't be afraid to go into detail when giving your opinion of a product.
• Compare to similar products. Feel free to mention other items you consider similar and how they rate in comparison to the one you're reviewing.
• Try to keep it short. The world wants to hear what you have to say about the product. The recommended length for a good review is 250 to 500 words.
• Have fun. Your opinion is worth something! Other users want to listen.
