Definition: Given an Amazon customer review, write a title for the review. The preferred titles are under fifteen words.
Input: The external quality materials are ver y good and resistent to shocks and bad weather conditions, however I expected it to be faster. I make the comparisons in time with cheaper pen drives, transferring small files, larger ones or a mix of them. However, the best ratio was 2:1 which I expected to be a higher ratio.

Good quality, speed not as expected
