Review on Never Lose Your Lens Cap Again - Zeikos ZE-LCH1 Lens Cap Holder For DSLR Cameras by Kevin Caldwell

Works a promised with one exception:Strap [just a stretchy cord] is too short for a lens longer than a standard lens.I bought it for my NIKON D90 with 18-105 lens . worked fine for a while but broke the cord after a month of use.If the cord were longer I'm sure it would not have broken!Easy fix . I replaced the 'cord' with a much longer 1/8" black ribbon from my wife sewing supplies.Can remove the metal clip at the 'lens barrel' area with needle nose pliers and the 'dot' decal comes off easyon the 'cap end' so you can rethread any length cord you want. Just make knots at the cap end and the lens end sothe keeper is secured. Works great . no tension on the keeper!Then again just buy another "Keeper" they are so cheap!Joe
