Query: Excellent product. Do follow instructions when putting on!

I ordered those before trip to NH. Arrived on time. I tried to put them on - and had similar filling as person below (who rated at 1 start) - didn't look as fit. I rechecked the instructions - turned out I closed the bottom outer (closer to you) clip first. Unlocked it. And everything worked perfectly. 2 hours later plowed through steep icy incline like nothing. The same road I had trouble last year.This product is worth every dollar.Note: remember the inside clip has to be locked first.SCC install video: http://www.scc-chain.com/Videos/Super-Z6_a_h.wmv
