These savers are beautifully thin, light and easy to move. I ordered 3. Two were at the bottom of a huge box with no packing whatsoever between them and the box. (There was heaps of packing on the other side though)! Even so,the savers came through unscathed and were perfect. My wife loves them, and they do look good. As others say, they are not clear, they are partly opaque due to very fine patterning on the top. That makes them look better though.
The third saver was in a box - inside the main box, excellently packaged. However, it ought to have been a reject (probably was). it had several small patches of fine scratches on the underside. Viewed from the top; these appeared as white patches. Also on the underside, near a corner, there was a 'pip', or very small lump of glass sticking out. Viewed from above, this looks like a white 'spot' or very small white circle that needs wiping off.
We had several problems at the time and complaining about being 'sent a second' wasn't a priority, so we never complained.
If you are lucky and get non-rejects, these are extremely excellent, well designed, worktop - enhancing savers. Well done Joseph Joseph. But in future destroy any 'seconds' to protect the consumer and your reputation.
