For me, better than quarks, but not as good as quantum techs
I love these tools. I think they stick better than the Petzl quarks. I had more consistent, single swing placements than my petzl quarks. They look freaking great.
My only complaint-made in china, while grivels and most of petzls products are not.
These used to be my favorite tools. I owned them for a while but sold them and bought the grivel quantum techs. The quantum techs are noticeably lighter and have a better angle for me. I think the quantum techs are the best kept secret regarding ice tools.
