I haven't replaced my 1010 ebq since it got stolen; but when I still had it, I had a problem with the micro adjust moving by itself when I was routing deep mortices in jambs to insert cups for multi point locks. I ended up turning it all the way in one direction to lock it up on purpose.
I also replaced the depth stop bar 2 times after it got bent, when it had taken a tumble from the top of the CT to the floor after someone snagged his foot behind the hose when passing. With the OF 1400, the depth stop rod is protected by the tool housing, so it won't bend when it takes a small fall. (but I find the OF 1400 too heavy for vertical work in multiple passes)
