I just got mine this week & I love it! It fits so much better in my e-cig case than the bigger version & still puts out the same performance charging my batteries in the same amount of time. It may be little, but it sure is mighty! Plus once again Dragonfly has the fastest service! I give this & Dragonfly 5 stars, which shouldn't stand for "Good" rating, it should stand for "Fantastic"! Thank you Dragonfly, YOU ROCK! Rating: [5 of 5 Stars!]
