Query: A nice product with a small drawback

I purchased one of these lens adapters instead of the Canon product because I already had several filters and hoods for the 58mm threads. It is a nice product. Sturdy black anodized aluminum as opposed to the Canon product, which is plastic. I can't detect any vignetting or flash shadows caused by the lens adapter, but adding a lens hood does create problems. I leave the adapter on the lens with a skylight filter just to protect the objective lens element, which is exposed. Looks good on the S-3 so I just leave it there. Only problem is--the tabs that lock into the bayonet mount around the S-3 lens are undersized. The adapter locks into place OK, but then it's a little loose and rattles in the mount. I put some tape around the tabs to take up the extra space until I can find a better solution. That said, I like the product.
