Lunar made it slow down somehow. Finger flicks were more effortless and satisfying before lubing. I put it on the largest travel distance and lightest spring compression, and I've had no popping issues. I find it can be pretty catchy, though. I'm not sure how different the dual-adjustment settings are, but I think I prefer it on largest travel distance and tightest spring compression. It is a little difficult to finger trick sledge hammers, but I think it's the easiest on this cube compared to other corner-twisting puzzles (e.g., the Dino cube and the YuXin 8 Petals). Lining the corner caps to put them back on is a little difficult. It's best not to remove edge pieces, because you might end up separating the edge from its feet, making it difficult to reattach them. I like how it's lighter and easier to turn than the YuXin 8 Petals. However, it does feel cheap for its price. I don't think it's worth its price, so I recommend getting it on sale.
