I have a 2010 Cheetah and never have had an issue with it. I did however had to replace the string it came with. I had to get a custom string cause the 2010 strings were terrible on the Gold Series bows. Martin. If you go on Martin's online store you can buy a metal module for your bow. I did and replaced the plastic module I had. The threads were better on the metal module and the bow made less vibration with it as well. The bow is good just needs to be tweeked a little it seems like. Martins Customer Service has been good to me.
