Query: Loose fit? Should I have stayed with Canon?

I didn't want to pay a lot for a Canon battery grip so I went for the Opteka. I previously owned two Canon brand grips and I was a little unsettled to find that with the Opteka I couldn't make a tight fit with the base of the camera-in other words, if you held it up you could see light coming through between the grip and the camera bottom. Also, the tripod thumbscrew wouldn't tighten any more and I was afraid to use more muscle lest I strip or crack something. And the battery insertion method from the side is borderline Rube Goldberg. Maybe I shouldn't have been so cheap?
