Based on the brevity and limited information, I would rate this review a 2. While it's a positive review with the words "very good," it lacks sufficient detail and does not provide a clear understanding of what specifically the reviewer liked. To be more helpful and informative, a higher-rated review should include elaboration on specific aspects that made the experience favorable, as well as any constructive feedback if relevant.<|im_end|>

 I would rate this review as a 2 out of 5 in terms of its usefulness and detail. Here's why:

* The review simply states that the product is "very good" without providing any specific details or examples to support this claim. This lack of specificity makes it difficult for potential buyers to understand what makes the product good and whether it would meet their specific needs.
* The review does not provide any information about the product's features, performance, or any other relevant details that could help potential buyers make an informed decision.
* The review does not mention any potential drawbacks or limitations of the product, which could be important information for potential buyers to consider.

Overall, while the review is positive, it is not particularly useful or informative, and therefore I would rate it as a 2 out of 5.<|im_end|>
