Helmet question

Looking for an affordable race helmet and came accross this one.

Just wondering if they are any good. Or if someone else has an alternative that's not too expensive. I'm going to take my car to the track in about a month and I thought I should get a helmet in case I break into the 13's. Hopefully I'll have no trouble getting there.
