Very good however some centres need re-fitting as are loose. This time some missing. from Anonymous on 20/06/2016
Previously I have been very happy with this excellent budget product. Some centres have been loose, however it has been a simple job to glue back in place. This time there were more than usual - 12 out of 100 of which four of the detached centres were missing.

Out of 100 - five are cracked or the glass otherwise broken, three have the metal insert detached. I am not sure I can trust this product for the intended job, which is a shame.
