In one week, this has become my favorite fidget. Much to my surprise, the motion that I've connected with most is flipping the top one, a motion not pictured in the marketing material. The magnets are just right. I suppose my only desire would be a slightly bigger size, but I also acknowledge my hands are quite larger than average. I'm already thinking about ordering a second one for home-- have you thought about doing one in titanium like with the rollers?
