That's the kit I have, and to be honest it is a bit "Heath Robinson", but for £15 and a little adaptation to suit my personal preference of installation, its great.
I use it all the time now, I bet during the day in my business I open the boot 6/7 times, and have done so for the last 18 months. In fact I have to remember to use the key sometimes to prevent the lock from seizing.
But everyone to their own I suppose.
Like I say, for the money you're not getting perfection and you will have to ditch the rod and come up with a bit of bicycle brake cable, but after that ....."nowt wrong with it"
