I use a scott extreme stalker which is the same mask and I have been very happy with it for many years. I bought the defender for my son to use and it works just as well. On the reviews it is rated just over 5 while the scott is rated an 8 go figure. This mask fogs easy but if you exhale through your nose this doesn't happen. Doesn't protect your neck very well.Looks cool and you can wear a hat with it.
This is a good inexpensive mask that works very well. Once you get used to using it you should have no problems. I would buy one again.
