When I had lost the original lens cap from Canon, I was just very sad. But now I'm even really happy! Because of this cap is much better on the lens securely in place firmly and slips when entering and clearing out of his pocket, or as in my case from the backpack, no longer permanently from the original. The build quality is very solid and tidy, there are no sharp edges or muddy processed areas. The snap lock can be very easy to operate and by the backup tape, I will probably not lose this lid now. I have secured the very stable tape the harness and quite near the eyelet for attaching the belt where the belt is still yes twice, and since only the lower part of the belt. The backup tape then about 15 cm leeway, so that even a slightly larger lens can be protected. I use only once the EFS_18_55 and there's really room for maneuver until the band is tight. I have had very good experience and would recommend this lens cap with a clear conscience!
