Think about it
I am surprise and skeptical because if you go through the reviews the bad ones are really well detailed and customers explain every thing, if you go trough the good one they are really short and sometimes in a poor English and I notice that one of those were identical from two different people. How many chances are that two person write the same reviews in a broken English one after the other? Also, why instead of be exhaustive and talk well about their service people are so concise? In my opinion if I have to write many reviews to increase the rating I'll be bored with be exhaustive and I'll probably be short and concise. Just saying.
