I bought a 2010 Martin Cheetah over the winter. I thought it looked like a great bow for the price, so i went for it. I hated all of the factory accessories that came in it. They were advertised as different brands than what were in them. It had a cheap dim 5 pin sight, a horrible factory quiver, end a quickened 360 rest that made a ton of noise on the draw, so I put an octane stabilizer, extreme sight, fuse 3 arrow quiver, and qad drop away rest on. I then had to put on the sts and limbsaver buttons because this bow was soooo loud. After I started singing arrows I found a lot of string wear happening on the cables, and shooting string. I found a ding in the idler wheel. The ding was mostly on the outside edge, so it appeared it was just the extreme string angle causing this. I ended up getting new vaportail strings and cables because or the wear, and poor quality of the factory strings. I found the factory cable slide was shaving the cables and causing wear, so I replaced it with a Saunders hyperglide. I just started shooting the bow with the new strings today, end my f7 cam module totally bent over to the side, and the string went odd track in the cam. I don't know what to do. It seems I have one problem after another, and am seriously thinking of getting rid of my Martin and getting a different brand. I have not gotten any help from customer service, and am sick of putting money into this bow. I bought it in a budget, and it turns out I had to spend more money than I wanted to in the first place. I am just looking for advice. Do they make metal cam mods? Do all cheetahs suck?
