Lunar made it slow down somehow. Finger flicks were more effortless and satisfying before lubing. I recommend using Lubest XMT 10; it worked much better Lunar. 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 have fewer catches/lock ups on the smallest travel distance (6) and tightest spring compression (9). It is a little difficult to finger trick sledge hammers, but I think it's the easiest on this cube compared to other corner-turning 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 think its price is a little high for what you get, so I recommend getting it on sale.
