I love mine, admittedly,I had a set of B and Q specials prior. I use them at least once a week and in between they are loose in the back of the pickup. I confess that I have used them to carry deer out on occasion.
I really like the ability to track horizontally and haven't suffered with the rifle jumping excessively, it's normally a 30-06 so has the potential to jump. I drape the sling in front of the hand grip and hold it, works pretty well.
I think you can get spare yokes for the front but if you broke the hand grip I expect that would be a problem.
I should probably collapse them and put them in their bag for transport, if I used them less often I would.
