Input: Consider Input: I wasn't expecting such a good cover for the price. Nicely built, better than some cases that cost twice the price.

Output: Positive Review

Input: Consider Input: As others have noted, the failure rate on these is quite high. Out of the three I purchased, two failed within the first 20 cycles. One is still working 6 months and hundreds of cycles later.
