StudioLive Issues

I have been a long time fane of the studio live boards . I Run an installation company for over 15 Years . I was recently working on an install in a church and had recommended the Studiolive 3 board . We received the unit I opened it and and was damaged . ( This unite was ordered directly from the factory ) . We had to let the church borrow our demo unit while the unit was replaced . I sent back the damaged one and Presonus sent me a new one . I open the box to review and there was no sign of damage and everything looked good . Plugged it in and check the unite to make shore sound was coming out and everything was good. Then out of no where the unite cycled off and turn on by it self. The unit showed sound coming in but no sound coming out . I trouble shooted the unit to make shore something was not routed correctly , mutes or discoect but nothing worked . I even tried to reinstall the driver but nothing worked . So it looks like I have a bad unit . So now I have to return this unit again and get a new one from Presonus . Then to put the icing on the cake I just received a call that the Studiolive 3 board we let the church use while we are returning the bad unites is freezing up during there services . This has been a very bad experience with this board . I get that a new board may have issues here or there but this is major issues . I am questioning the quality of this board. To have three back to back units be damage or defected concerns me as engineer . This has caused my company money having to send installers back in forth with these units have to reimburse money to the client for the inconvenience. Don't know if i would recommend this board . To many issues
