Very interesting. I've been using FLEX since I came to Autogeek, so 10 years and have never had a single problem. In fact, for most of my detailing work I use the BEAST and now the CBEAST just to go as fast as I can while keeping my quality high.
I take all the popular tools to all my classes and let everyone use them and make up their own mind. They are the predominant tool used in my boat detailing class and detailing boat is really hard on tools.
Like I say, your experience is definitely interesting and I would also say the exception from my experience answering questions on this forum, on FB and teaching classes for years now.
I'll share this thread and your comments with FLEX. I'm sure they would like to know of your experience.
