I was offered a new unit at a discounted price. So no, it was not repaired or replaced under warranty.
Frustrating, but what can one do?
Complain and Complain and keep Complaining until someone does something to stop you complaining!
These forums are a great place to express your frustrations at manufacturers who won't honour warranty claims as these are the people who buy their products! I own two Inon Z240/4 and have no problems with them, but I can tell you this recurring theme of overheating issues worries me sometimes! The company obviously knows there is a problem but wont address the issue other than to give vague guidelines on how to prevent the possibility of it happening.
