Update!!! In addition to my previous review, today I used it for the first time and it came with a security alarm sensor from the store apparently where it was bought from originally ... I had not noticed it until the alarm came on at a store! So it was resold to me... probably could have gotten it at a discount store for less ( from where it came )

Not sure if it is authentic...hopefully it is.. but I  have one similar to it and has different design in inner fabric and front MK letters are different in format.. also mine came defective.
