Fantastic
Size: 17inch, Size: 17inch
I absolutely love these for my garage. An absolute must to have to elevate functionality, and space as a whole. Great upgrade. If you get a metal sheet to attach it onto without any screws- perfect. One down side is you can’t put too much weight on it if you are not mounting it by screws obviously. But holds my wrenches like a pro.

The Force is Strong with This One
Size: 12inch
These are pretty robust and strong. Wish they also sold 18” and 25” models, but imagine I would never be able to dismount them. Ordered some more because I ran out of room on the ones I bought.

Half product
Size: 17inch
Only one of the magnetic strips were actually magnetic. 3 stars cause only half of the product worked.
