The first strobe I had did break where one lead from the Big Honking Capacitor" (nice choice of words) went into the circuit board. They were so cheap I just risked using some translucent caulk I had used sealing my sliding porch doors. I squirted the goo under, and around the big capacitor, half burying it. After the stuff set I screwed the casing back around the circuit board and put the yellow-clear plastic cover back over the strobe tube. No problems now. I zip-tied it to the front of my rear rack so that light would flash in all directions. I also take it off the bike and use it on my two person kayak once a year when the wife and I paddle out into Richardson Bay to watch the fireworks offshore of Sausalito.

As far as ruggedness I have bent my handlebars going off-roading on my touring bike yet the strobe keeps working.
