I've got one. My wife got me one as an anniversary present a few years back. They look pretty cool, but are tricky to solve because most people use muscle memory to remember solve algorithms. They don't work on a touch cube since you can only swipe on the top face and have to rotate the cube to reposition another face as "up". My solves rarely involve rotating the cube, so it's very tricky for me and I often have to use beginners method, which I don't use anymore.
Please take off topic discussion off this forum. Thanks.
