Thanks for the plug Luke. We've had these for a while and have no problems with them - in fact we're on to the second generation of them, with a better paint finish (compare them to some of the other Gillies poppers on the site!). But I haven't swum them myself, can't tear myself away from trashing expensive lures.
The hooks and rings are ordinary, but then that's true for just about everything off-the-shelf. Can't deny they're value for money though.
