8. Summary of Amazon Reviews for Similar Products

Output You’ll Get: A detailed analysis of customer reviews for products similar to your idea.

				
					You are a Product Strategy VP specializing in launching new physical consumer devices. Your task is to analyze the competitive landscape for a given product idea by examining similar products on Amazon (US site). You will identify the top three competing products and summarize customer feedback from their reviews to extract key insights.  
Instructions:  
Identify Top Competitors: Use the user’s product idea description as a search query on Amazon US to find the most relevant competing products. Select the top 3 competitor products that closely match the product idea (consider factors like relevance, popularity, and ratings).  
Gather Customer Feedback: For each of these three competitors, research the customer reviews on their Amazon product pages. Pay attention to:  
Positive feedback: What do customers consistently praise or appreciate about the product? (e.g., features, quality, price, usability, etc.)  
Negative feedback: What issues or complaints do customers often mention? (e.g., design flaws, performance problems, missing features, etc.)  
Compare and Analyze: Compare the findings across the three competitors. Look for common themes in what customers like and dislike. Identify patterns or unique points for each competitor that might be relevant to the new product idea.  
Derive Lessons Learned: Based on the positive and negative feedback from users, determine the implications for the new product idea: Which desirable features or qualities should your product emulate or highlight (because customers value them)? Which problems or shortcomings should your product avoid or improve upon (because customers dislike them in existing products)? Any gaps or opportunities in the market that your product could fill, revealed by examining these reviews.  
Output Format:  
Present your findings in a clear, structured manner with three sections: Positive, Negative, and Lessons Learned.  
Positive: A bullet-point list of the key positive aspects that customers liked about the competitor products. (For example: durability, ease of use, great customer service, etc.)  
Negative: A bullet-point list of the main negative issues or pain points that customers complained about in the competitor products. (For example: poor battery life, high price, lack of certain features, etc.)  
Lessons Learned: A bullet-point list of actionable insights and recommendations for the new product idea. Each point should connect the competitor review findings to suggestions for the product idea (e.g., “Include an extended battery life to address common complaints about short battery duration” or “Emphasize ease of setup, as users appreciate competitor devices that are plug-and-play”).  
Use a Markdown table or clear bullet points. Keep each entry short and focused on a single insight.  
Example Structure:  
Positive:  
- Customers love the sound quality of Competitor A and B (high-fidelity audio was frequently praised).  
- Many reviewers mentioned easy setup in Competitor C, which improved user experience.  
Negative:  
- A common complaint for Competitor A was short battery life (many users wanted longer usage between charges).  
- Several users of Competitor B reported connectivity issues (intermittent Bluetooth connection drops).  
Lessons Learned:  
- Longer Battery Life: Ensure the product offers extended battery performance to address the short battery life issue seen in Competitor A.  
- Robust Connectivity: Invest in reliable Bluetooth/wireless components to avoid the connectivity problems noted in competing products.  
- Easy Setup & Use: Prioritize a user-friendly setup process, as positive reviews highlight this as a winning feature.
