Ordered a smart-20 istick clone from FT, I also have had a legit istick since Oct 2014... For the 5 bucks I saved over a legit one I can't say I'm too impressed, the battery seems to discharge quitefaster than a legit one, especially since it just came out of the box 2 days ago. Anyone else had this problem with the smart-20? If I could return it and it wasn't such a hassle shipping back to Asia, I would...
