So this was my first teraminx, and I’m no speed solver. Got this for casual. I didn’t realize I would have so many lock ups. I found when using it in a table, it worked great. But it I feel like the pieces a bit loose. Like there’s a lot of spread between the pieces and if you go too loose on the **** tension, you can pop out pieces which has happened to me. But too tight, and it is harder to turn. So I think you can find a decent balance if you want it to feel really good. All in all, it’s pretty nice. I’m still perplexed how I’ve seen some people speed solve this thing without any lockups.
