I own 2 Aculeus. A 175 and a 460. I change the string on all my bows every year and cables every 2 years. I probably have about 800 shots on each of these bows every year. Both bows have been trouble free. I have had the 175 since it came out a few years and the 460 since the end of first year it came out. They are extremely accurate and easy to change string and cables and tune without a press. I put about 30 shots on a new string then tune bow and have never had to touch them again untill I change cables. My string and serving are still good after 800 shots and could go another 800 but I get string and cables from Marty at a third of the cost of a manufacturer set and they are better. I keep my string waxed and put a small amount of black Lightning on center serving every 15 shots.
