Clive, like Wayne said, it's very quiet and like you said, doesn't engage properly and just doesn't seem like it would last. Mine are taped in the "OFF" position because I had a habit of accidently engaging them the way I palm the reel when I cast.
I'm sure the reel is for ok trolling but, it'd be one of my last choices in this category of reels due to the high gear ratio and poor clicker.
