I did use it about 6-7 months. Great device never hang in any process. Nice slim device. 2b ram + quad core processor makes it smooth.
Because of slim design glass can easily break.
Im very disappointed because it have only 1 tray for 2 sim card if you want to extend memory with adding memory card then you have to remove 1 sim which makes it single sim phone because out of 16gb you will get 10 gb and 10 gb is not that much.
So it is great device if you are a regular guy then you can definitely buy this.
