I'm thinking of getting one of these, but reviews online seem pretty mixed, with quite a few people saying they're a bit flimsy. I'd be interested to hear the views of anyone who's used them, or anything similar. At the moment I use quad sticks - I really like the stability, but turning them with the rifle resting on them is not a smooth operation, to say the least. That's why I like the idea of this rest, which seems to offer stability whilst also being able to turn and tilt smoothly. Any views/ thoughts on it gratefully received. Thanks.
