I've had 3
HH90 motors in the course of a year.
1st one DOA out of the box. Replaced by
Sadoun.
2nd one died 363 days into warrenty (they based it on 1st purchase....) Sent to Sadoun, they took a look at it and declared it "bad". Would not do anything to help as it was considered out of warrenty. Sent it back to me (collect).
I contacted
Stab manufacturer in Italy, as the warrenty on the paperwork with the motor said "2 years". They pointed me to Fortec Canada.
I sent the motor to Fortec Canada, they sent me a replacement. Nice Folks.
This one worked for a while, then not sure what happened either the dish got wind-blown out of alignment, or something went wrong as the dish will not tune.
Admittedly, I have not been up on the roof where it's installed to check/re-align - but this is not at my home, so it's not a high priority.
I'd have to say the HH90, at least for me - has a dismal track record.
