Hi guys, I'm new to the forum and was wondering what cube I should get. I currently have an mf3rs, an mf3rs2 (which I bring to school every day), and a gts2m which I don't feel comfortable taking to schoool because I've heard that the magnets are prone to falling off. If I get a new cube what should it be? I'm looking for a slightly more stable cube, and was thinking of getting a valk 3, valk power, or a gan 356 sir sm. What do you recommend?
