PA floor guy said:Seth your correct. In all counts. As far as my traveling with the tools. I have a racked out sprinter, all my vacs have a home. They dont fly around in the van. These vacs have all broken from normal use. Believe me, I take good care of my festools.
Unfortunately 'normal use' isn't particularly measurable. You'd probably think I baby my tools but for me that's normal. So far my 2 vacs are doing fine, but I don't recall them ever even tipping over. Mine aren't being transported much in vehicles either. With very different conditions my breakage is 0/2 while yours is 5/5 so it's reasonable to think it is related to something you are doing differently in your normal use. Clearly your normal use exceeds the strength of their design, but without knowing the exact circumstances of the breakages it's not easy to assign responsibilty.
