I like the look and durability but because I thrash around a lot in the roughest terrain I love the internal clutch system that keeps the chain from slapping around on the chain stay but more important keeps the chain from popping off! I use this matched with the trigger shifter and it work's like a dream! :Make sure it's adjusted right or dialed in correctly before ever discrediting. But I find it works great for this price point so if your on the fence hop off and give it a try I think you will see Box is legit.
