So I purchased a Rytera Alien z back in October from KM archery hut. I have shot the bow maybe 200 times since I got it and have had several issues with it. First the cam module screws don't stay tight I think the holes may be to large or something else I really don't know but I guess ill order a new module to see if this helps. Second the string is beginning to fray around my peep badly, and I now have to replace it with less then 200 shots. I think this is completely ridiculous being brand new. Has anyone else had any problems like this? I thought Martin made some decent bows but after getting this one and already dishing out money to fix it I am having serious buyers remorse!
