Query: Disappointed

I purchased this for a 50mm prime canon lens. Have always had good luck with Tiffen products but when it arrived I noticed the glass filter was "loose" inside the ring allowing it to shift around slightly and make noise as it "clicks" against the ring. I returned it without issue through amazon and they promptly sent a new one. Initially it seemed ok, but within a couple minutes of handling it presented with the same issue. I took a few pictures with it anyway just to see how it would do.....Big glare spots...which certainly could be due to lack of talent and skill but when I read other reviews glare was noted as a problem from some users . Either way the filter should not slide around and make any noise in my opinion.I'd add a photo with the glare issues but not seeing a link to do so. Someone with more experience may be able to tell if it is the lens, the filter or the user...
