This works fine for my situation. There isn't a good place on the camera to do so; plus, if the cap is attached to the body, it would be a pain to change out when I swap lens. The elastic band fit different lens just fine. The other end has the sticky pad to put on the lens. I know that elastic like this tends to wear out over time (doesn't stretch any more), so I am not sure how long these last.

I love these lights! Great lighting and very easy to put together.

For starters installation took some time due to that my old lock have different measurements so i needed to make close the old hole and make a new the instructions really helped specially the card that shows the measurements needed for the apps it was really easy to install and add key numbers also adding the RF card

Absolutely love this discs being collapsible and not taking much space. Great reflection, material, size.

I discovered these keepers after losing a couple of lens caps while hiking. The adhesive stays firmly attached to the lens cap and the elastic is perfect for the lens. I no longer have to fidget around with where to put the cap, just pop it off and pop it right back on.Additionally, Digital Goja was extremely quick to ship this to me! I am very pleased with my purchase and will continue to order from them in the future.

I ordered this as a Christmas girt for our 10-year old granddaughter who loves producing videos of her American Girl dolls using an iPhone app. My husband opened the box to check out the kit and was pleasantly surprised at the quality of the tripods, umbrellas, the bulbs and the carrying cases, all sturdy just as advertised and reviewed. In fact, we were so impressed that we immediately purchased a second set, this one for our 11-year old granddaughter who makes instructional videos of crafting projects which she posts on YouTube. I am certain both girls will love these.

These should help me keep from losing my lens caps. They installed easily and quickly. The string could be a little longer but so far no major problem. The straps do not interfere with the camera action and it's nice to not have to juggle a lens cap while taking photos. Pleased with the keepers and the MagicFiber cleaning cloth is a nice bonus. Thanks--will buy from this seller in the future.
