Early this summer I wrote a negative review regarding the WOW disposable. At the time I had purchased one disposable and later received another one free for ordering. In both instances they had poor battery life (30 - 35 puffs each) and I wrote a review that reflected my experience. To date that review has never been posted. Makes me think the V4L reviews aren't a true reflection of the products sold. I did receive a free complimentary WOW disposable when I inquired about the problem I was experiencing. That disposable had a much better battery life (150 puffs). My guess it was newer stock. I didn't bother writing a review on that one since my other review was never posted.
