## Customer Reviews

### ⭐⭐⭐ Extremely Tight Fit
*by P***L on May 3, 2014*

Though previous reviews read quite favorable, the unit I received was nearly impossible to slip over the lens without scary-hard forces. Since it did not fit or seat easily, I used sandpaper in the inside edge to widen the inside diameter. Now it will properly seat over the lens. The packaging came with a little scratch-off 'seal of authenticity', which makes me wonder if Amazon shipped me a knock-off version?? Once installed, unit works fine. It does add about 1/4" of length to the lens.

### ⭐⭐⭐⭐⭐ Blew Away My Expectations
*by S***" on July 12, 2013*

My major concerns in buying this were with the quality and fit of the product. This item is of high quality, and has been accurately designed. Its fit and finish are complementary with the MX-1; does not look at all out-of-place. The spring mechanism works great. Have no qualms using it as a almost full-time replacement for the standard lens cap. I was concerned that the petals might extend slightly into a wide-angle photo, but checked this closely and could discern no problems.PROs* Fits external lens barrel very well. Friction fit, but tight enough that I can't ever see it accidentally coming off, yet can still be removed by hand. Have worn in cargo pockets without any slippage.* Door tension seems perfect: opens and closes smoothly, without hampering lens extension.* Does not interfere with zooming or focusing in any way.* Design and finish are complementary with the MX-1.* Workmanship and tolerances are great. Petals quickly open and close without binding, yet it is difficult to see any gaps between the edges when closed (maybe 1/64 inch?). I wouldn't hesitate to use this in almost any environmentCONs* Adds about 1/4 inch to depth of camera. For me, since this isn't a truly pocketable camera, this size increase is not very significant.* Protects lens from a hard, direct blow by an object less well than the standard lens cap. But you would probably have to ram it directly into some hard object to have any problem. Glancing blows, or carrying in a case with other objects should present no problems.* Obviously will not provide as good a rain or dust seal as the standard cap. However, the MX-1 is not advertised as being weather resistant, and I wouldn't normally be using it in harsh environments. Anyway, the tight tolerances on the fit of the petals should help, although I would probably switch to the regular cap in bad weather.Overall, this cap has exceeded my expectations in every way.

### ⭐⭐ Two Stars
