Top critical review
Not well thought out and over priced.
Reviewed in the United States on October 21, 2019
First, there are only 10 widgets per box, requiring several boxes if you have several sets of wrenches. Second, they're overpriced for what they do, costing $2.50 per wrench to organize. There are more reasonably priced options out there. Third, the magnets aren't strong enough hold the widgets tight to the drawer. The set of 10 connected together has a hump in the middle due to the way they snap together. Fourth, the wrenches are held vertical so you can't read the sizes and there's no method for identifying them or room to mark the slots yourself.
On the plus size they're modular so you can use fewer than 10 if your needs dictate.
I'll probably seperate them and use them for odd tools to keep them from moving around when opening/closing the drawers. Or I might return them considering the price.
