I have no complaints about the cube itself. Right out of the box, the turning is good for the price and easily adjustable with a single included tool. The battery life is incredible, and for all the features packed into this cube, the weight is comfortable too. Notably missing, however, is a gyroscope. But the real miss here is the CubeStation app. I don't know how much better it is on iOS, but the Android version is a miserable experience. Much of it is in Chinese, bugs litter every section of it, the interface looks and like it was ripped from some bad mobile game, and most of the features of the iOS version are nowhere to be found. Fortunately, if you just want the timing functionality and solve replays, there are alternative websites like Cubeast or csTimer. Either of those is a significant step up from GAN's own app. Overall, the GAN 356 i Carry 2 is a great cube which is held back by its terrible excuse for an app. Don't let that keep you from picking one up, though. I've been regularly practicing with this cube after I picked a better app to pair it with.
