Not worth the price
The video they produced is misleading as it shows the installation to be easy. To the contrary; the adhesive is not strong enough to keep the bracket in place (on the wall) when attempting to remove the shelve as the bracket post and the post hole are a very tight fit. Out of the 8 brackets (for the 4 shelves I purchased), 6 required me to pry the brackets from the shelves with a screw driver prior to attempting to install. The install failed. Now I have purchased more adhesive to see if I can make this work (may have to somehow make the post hole a little larger).  Return shipping is too costly. I have wasted so much time on this project.
