Promaster Polarized Filters, any good?

[illxpanda]

While searching around some local stores, I stopped by Penn Camera and saw a promaster circular polarizing filter. The price seemed reasonable so I picked it up. I haven't done any tests yet, those will come tomorrow. I can't seem to find any reviews on it. I was wondering if anyone has tried a promaster filter and if it's any good,or should I return it and get something pricier that is top quality?

(I am willing to return it and purchase a more expensive one, but being a beginner, I don't need the best and probably won't use this very often in general)
