Product features a spray bottle of lens cleaner. This is not what was received. Received a 1x1 sealed pre-moistened lens cleaning cloth. This is hardly a "kit" and not as advertised. The arm sleeves and nose pieces were easy to put on and are as advertised. However without Prime shipping -- an additional cost of 5.00 is incurred; $21.00 seems to be overly priced, especially if you do not get the "Kit" as advertised.No cleaning kit includedTheses are so easy to put on and they are a great price .After playing around with it they fit greatLiked that it can with two nose pieces as that is what we keep losingfast delivery i got what i would thanxFit is perfectThey fit but, they are not the real deal. It doesn't say Flak 2.0 on the inside of the ear piece. So that tells me they are fake.
