Instructions: Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.
Input: This is a PERFECT companion.  Well designed, matches the Nexus  7 (almost perfectly). My only complaint is that the keyboard must be manually turned on with the little switch each time, rather than auto recognize when the Nexus 7 is docked.  All functioning keys are here. It DOES have a Tab key, which sets this keyboard above the others.  The case fits tightly around the Nexus 7.  Have no complaints when it comes to doing EXACTLY what is advertised.
Output:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
