Got the replacement yet ? After reading your story I checked mine for the screws coming loose. Everything still tight so far. Have only done a couple cars and one nasty boat as of now but its doing OK. I still find myself reaching for the Griots over my Megs v2 or the old PC. Getting spoiled by the power I guess.I tried a
Flex 3401 before I got my current da's and didn't care for the forced rotation compared to the random action.The available
backing plate size selection weighed in my decision also.Might be something that I would eventually get used to.I did like the
Flex 3403 rotary but will have to wait till the Makita dies .Good luck no matter which way you end up going.
