Last week I used this on a Nikon DSLR, SONY 4K camcorder and Canon camcorder. I could easily adjust them for each camera. I made a small hole in one for an overhead mic to mount off camera (donate the mic). All cameras remained dry, only the glass on the lens was exposed. They have a drawstring that stretches around the lens and keeps all the electronics dry. I don't think they will stand up to repeated use. Think of it as a disposable item.
