Review on Invisible Plate Hanger: Flatiron Disc, 4-Inch - Innovative Solution for Displaying Plates by Chip Palmer

I was encouraged by the many reviews of these turntables. I have ordered 3 times from 2 different sellers thinking it would be a great item. I followed the directions down to the letter "T" (cleaned the surface of the plate, mixed the glue very well with my finger and spread it around the edges, placed the disc on the plate and left it for 24 hours. My first reaction was, that's great, me will be ordering more!In a week the first plate came off the wall the pane came off.Luckily it was hanging over a padded cupboard and didn't break.Another plate I hung next to the first one it always hung until I took it off the wall to hang it up on its own again. When I took it off the disc fell right off the plate! So now I have to take care of returning the discs, which I got after three orders, around $40. I hope , I don't have to pay for return shipping etc.
