We have been selling plenty of them at the shop with nothing but praise so far -customers love them. (XLR8 and regular monsters). The only complaint I can really make is the toughness of the draw force curve-and moreso the way they will rip your arm out of your socket letting down. That said, it draws nicer than the Omens we just got in (apples to apples) and speeds are pretty much same-same.
In fact it's kind of funny- I didn't care for the demo Monster at the shop- saw "issues" but the production models are excellent and they ironed out the issues (same prob with the early Reezens-current models are worlds better than the first bows). The Omen is the exact opposite-I absolutely loved the Demo bow the rep brought by, production models we got in last week totally turned me off - and I was ready to lay down the cash for one.
