S30 Visor- I purchased a pair of them since they were cheap, figure to have one as a back up. I've worn them for 15-20 ice slots coaching & reffing, been fine so far, no fogging no scratches. I mentioned in a previous post they seem to have some random "fish-eyes", they are only noticeable if you look for them, not a problem in use. One problem I did find was helmet fit. I started to use it with a 10 year old Bauer HH4000L. With the visor extended all the way forward, it was too tight to be comfortable. I had less then a finger space between my nose and the visor. At the top, the visor was in contact with the helmet, no real top vent area was left open. It was usable but claustrophobic. I transferred it to a CCM 452, maybe 5 years old and it has plenty of adjustment space. Some may like the tight fit, I certainly had no need to worry about getting a stick under the visor. Maybe the screws for the J hooks are far back on that helmet model not sure.
