Sorry, there was so far used every lever of Delamax after 1-3 inserts (evenings = 500-1500 tripping) broken !! Some thought a little longer, some only a few hours. Most defects a broken cable in the molded strain relief equal to the housing output is produced - from the outside absolutely not visible.
Alternatives are unfortunately hard to find, as I have had a very bad experience with other manufacturers from the Far East (Photixx, JJV).
CONCLUSION:
Who needs the trigger only for occasional long exposures that could have longer his friends about it. But if you want to run Photo Booth many other similar stories so - and are likely to be most at a cable length of 5m - the only annoy !!
My tip: If not absolutely necessary, then AWAY !!
