Sensei SDR-4948 reviews

49-48mm Step-Down Ring is rated 3.7 out of 5 by 3.
Rated 5 out of 5 by from It works Used it to attach a 2x magnifier lens to a binocular microscope. Works fine.

Rated 1 out of 5 by from Wrong product for my flip mirror The outside diameter of the step down ring is about 1/32 more than the outside diameter of my flip mirror. That means that I can't insert the flip mirror into my 2 telescope focuser when the step down ring is on the flip mirror.

Rated 5 out of 5 by from Accurately machined I put in a 48mm filter which fits beautifully, with out jamming. I purchased a 55 to 48mm stepdown from Sensei, which unfortunately jams when the same filter is threaded the last 1/2 turn. Not sure if the quality from this company is consistant.
