Review on Set of 4 Multipurpose Cargo Organizer Blocks for Car/Truck/SUV/Van Trunk Storage, Designed to Fit Wool Trunk's Carpet by Maurice Morris

I was looking for a way to control things in the luggage compartment of my SUV. they do their job very well. There are 8 black plastic pieces in the box (a typical image on Revain shows 4 pieces. This is for the "set of 2" version; the "set of 4" version has 8 pieces). some velcro-like material on the bottom, meaning they're held onto the carpeting of my cargo hold. I used two pairs (two 90 degree angles) to secure the laptop. and he didn't move. The velcro is not very aggressive, making it easy to move as you please. Tip: Ignore the fact that the indentations give the impression that any two parts have to meet somewhere. There are four "A" parts (my terminology) and 4 "B" parts. Each pair of A joins B to form a pair of corners (two pieces join to form a 90 degree angle).
