I really like the Robot!! I did give it a 5 star rating even though it could be improved if a few ways. One of the main things needing to be improved is how you place the cube into the robot and take it out! The push button should open and so you could just pick up the cube or set it down in the robot then clamp itself in, because setting it to practice FLL scrambles takes so much to put the cube in and out makes it take so long for practice. The Robot sure solves the cube very fast and I like to watch it. I gave the fifth star for the case that comes with the Robot,, it is very nice and not a cheap cloth bag, it stores the Robot well and keeps it clean and all parts safe and clean, so I won't loose the little clear clips,, I would reccomend to Gan just to add one spare clear holder for the Robot so if you break just one then the Robot would not be down,, for all that use it is not an adult. Just as the App is way better now than when it first was released so I know they will make the Robot better,, and think it is nice and reveals to us learning the cube that it can be solved very very fast if we had the memory of the Robot,,, Ha Ha,, but it's works really well,, Though it is not a necessity it is a fun accessory to a cuber !!! Thanks Gan and to Dailypuzzles for a great price with the midyear sale !!!
