I'm very pleased with my limulus sticks
Its fair to say all sticks have negative points, that said the plus points of my limulus sticks far outway the negative
I tried a set of metal quad sticks, although they were adjustable it wasn't possible to adjust them in the field when a deer was seen, the limulus sticks I only open them wider to lower the rifle and they work fine on a slope where the metal ones didn't.
Also the metal sticks are very cold in the winter, and that metallic clink when knocked, carried a long way, where the wooden equivalent sound is far more acceptable.
A good bit of kit and don't go out without them
