This filter comes with its own case which I must say protects it extremely well! The build quality is really good and rotating the slider is super smooth. Setting this up on your DSLR is really simple, all you have to do is screw it on your existing lens (I used a Canon Rebel T2I). Here are the PROS, CONS, and CONCLUSIONS;PROS:-Beautiful build quality-Super smooth while rotating the density-Works really well with practice, just make sure you're focused because rotating the slider might catch you off focus.-Comes with a micro fiber cloth! HUGE bonus, you cannot go wrong with extras.CONS:I haven't found any yetCONCLUSION:You'll end up liking this fader, very versatile depending on what you're doing. I would really recommend this fader because I really enjoyed mine (still do!). Hopefully this was helpful for you :)Disclaimer: I am a professional product reviewer and was provided this unit in exchange for my honest opinion.
