i had posted here about my ets 125 sander that was seizing up after about just a few hrs of use. a festool tech was great and helped me isolate and try to fix the issue. I reported that a while back here on the forums. while the fix worked short term, the problem returned after 2-3 hrs of use. I sent the sander back to festool for repair. they turned it around pretty darn fast. it was within 3 yrs so it was a free fix. very pleased with the way festool handled it. fantastic customer service. thank you festool.
