Review on 3M Speedglas 9100 with Extended Coverage and Crown (06-0500-51) by Brett Slater

Just received yesterday, just got to class and was about to put it on, the first thing that happened was it was stuck and not moving properly, must have been a sign that it was too small at first but i tried to put it on anyway. Didn't know you can't remove it from your helmet AFTER it's FULLY ON if it's too small for that. Let's ask the instructor to help me fix the helmet. Buyer beware, does not work with Sentinel A50 which I am using.
