Aluminum rings can have issues with removal from lenses and filters, some aluminum rings are better than others. I believe Sensei is B&H's house brand or they sell many products from them. Better quality than most aluminum rings and priced very reasonably. Brass would be my preference for situations when it's placed and removed frequently but this will work well also. Thank you B&H for another good product.
Works great
Not much to say, except that it fits.
Smooth operation
A very good quality adapter at an inexpensive price. It does exactly what I needed.
Works - as it should. Easy on and easy off so you don't have to think about it or get anything stuck.
