I love my zigzag. Although I just found "the crack" last week. I thought they had that issue sorted out by the time I bought mine but I guess not. The guy from petzl called me yesterday and said he received my cracked unit and could send me a direct replacement now or an updated version on 11/22/14. I opted to wait for the new version. He said the new one won't crack. I guess we'll see. Back to the hitch climber for a while!
