Already in for service twice

Great looking unit, performed well and was easy to use. After 30 days, unit stopped working. Brought in for warranty repair and had to wait 30 days for new inverter(main component. Worked well again for 45 days, now same error message. Will bring in for repairs again tomorrow. Cannot live without one for another 30 days so I will probably get the GE profile model I had originally wanted. Will then give this one away to someone. Similar experience with Panasonic DVR. Was in for repair for three months after 2 weeks of use. I should have learned the first time. Will not buy another Panasonic product.
