Query: If you've never tried a B+W, get one and see the difference!

Pros:First of all, it feels really good in hand. I've played with other brands for quite a while, like tiffen, hoya/kenko, and the really cheap zeikos, and this was my first B+W product. It is well made with high class material. Your hand will tell the difference immediately.Secondly, the MRC really works. It looks like the glass is not there at all (of course there is still reflection if you look from a lower angle). Once again, I believe the product is #010M, not #010. Amazon has the wrong info.Cons:The water/dust resistive coating is not quite as advertised. It catches dust as easily as other brands (and my glasses). I heard that even keys could not scratch this coating, but I don't want to try this myself, even though I believe good glass must be harder than keys (Mohs scale 7 vs 4).It is also a little pricey... well, at least for me. I'm using it for my Tamron 18-270, and it definitely costs more than 10% of the lens value...
