This lens cap is easy to use. It snaps on, stays in place, and is easily removed by pinching the two buttons on either side.If you have a Canon G1X and use any filters with it, you'll need this -- the lens cap that comes with the camera does not fit the 58mm filters required by that model. This works well with a filter and filter adapter attached to the camera.I gave it 4 stars instead of 5 because it is a little expensive considering that it's just plastic, probably because it his the Canon logo on it. Also, it does not include a tether.
