I've been using one today, but I've got nothing to compare it too, and I've only used it for today, so I doubt my opinion carries much weight.
But it seems nice to use. It comfortably fits 100 meters of microbore; Gardiners reckon it'll hold about 120 meters max.
It runs smoothly and winds in lovely.
It doesn't fall over in the back of the van (though my van isn't very fast and I take bends slowly)!
Seems nice, but it doesn't seem really robust; a bit flimsy maybe? Time will tell I suppose.
