Floating Shelf Invisible Support Brackets Only - Concealed - 5" Hardened - Low Profile Blind Mounts for wall Shelving

In theory is a great idea but very flimsy and very hard to install

The posts of both brackets broke off when installation was attempted (by a professional contracting crew). They followed all instructions, including weighing the piece of wood. And I'm upset because I can't return them (wouldn't write a bad review if I could get my money back.) The break was at the point where the round post and the flat end meet. The post just came right out. There doesn't even seem to be any welding to join the two pieces and nor are there screw thread attaching the post to the flat end. I chalk this up to a bad purchase on my part. Buyer beware.

Great quality! very impressed with this product, makes some good looking shelves, confident with the support they provide.

Very flimsy, the post is loose on the bracket so that it will bend when you put any type of weight on them.

Item arrived on time. No directions were included. The post which is inserted into the shelf broke off from the base during installation.

I thought I was buying the shelf pictured. Oops. I did not want just hardware.
