Hi Dan Long Time No See !
Well not sure what job you have planned for this vehicle but its ok in open water so ok for Pipeline inspection but for most other jobs I would say not much good .
I found it not very stable and not much good in bad currents but like I said I dont know what your job is , For all I know you might be useing in lake or some thing .As for vehicle being reliable it was ok as long as you did not use full thrust all the time .
Sorry I am working blind here but its fine doing inshore work but offshore I would say No !
Cheers
