We have an 08 2588. Maybe 500 hours on it. It has been great. My main two complaints are very minimal. It used to jump out of rotor gear after switching gears, but for some reason, has seemed to fix itself. The inner engine radiator gets built up with light chaff on the bottom half. Vacuumed it off for the first time today, after maybe 500 hours. Very nicely refined imo from the 2388 and I bet the newer ones even more.
