I can not recommend this saver unfortunately. I had ordered two, but both had the same error. In parallel with the side mount ran a kind of crack. On the short sides worse than on the long sides. The terry cloth is cut at this point and there is virtually little slits in the lower film. In the photos you can see quite well. In my opinion, only a matter of time until the film tears and the bezel from the rest of the schooner dissolves completely.
