I do a lot of my charters "Direct from owner" and thus get close feedback regarding issues and how TMM deals with them.
Fortunately problems noted above have been minor and dealt with promptly and efficiently.(Otherwise I would not be going for 2nd round of ownership with TMM).
For instance, a guest reports that Genset had issue Christmas Evening. TMM met them at Soper's hole and replaced impeller... problem solved. Guests were very satisfied with TMM response.
Not all boats are maintained as well as TMMs. Thus the reason BVIiCatter (Post page 1?) chose to move his boat from CATCO to TMM.
