A friend at the field I play at had one of this on his Ion. He owns a shop, so this isn't really surprising that he had one already. It took him a little while to get it set up properly, but after all adjustments, his trigger pull was comparable to that of his Nerve, literally touch sensitive.
The shape is both a strength and a weakness because it makes it easy to squeeze with both fingers, but kinda hard to walk ( personal taste, I like my fingers super close together when walking )
I couldn't get it ripping, but he's used to a trigger similar to this, and he was either capping the Ion or getting damn close. Extremely short pull when adjusted properly.
The trigger seemed durable, looked hella nice, that's all I can really say, since I didn't get much time to get used to it.
Definately a worthwhile upgrade if you like your trigger pull short enough that you could blow on it to make it shoot. Shape is awkward, but he got used to it pretty fast, so whatever.
