The 75mm cap fits my 6-inch SCT rear cell perfectly—the anodized finish looks clean and matches my other gear. Washed out the threads once to remove a bit of grit, and now it screws on like butter. Solid little accessory for keeping dust off when not in use.

The 48mm cap threads on smoothly and fits perfectly on my scope's objective lens. The black anodized finish looks great and feels durable, should hold up well in my gear bag.

I've been using the 63mm cap on my finderscope and the threading is smooth and precise, no cross-threading issues. The anodized finish looks clean and doesn't pick up fingerprints like my old plastic cap did.
