I bought an 8 x 4 x 1.4 ft planter for my wife. It comes painted and the panels are protected by peel-off plastic in shipping. The screws and nuts in the hardware kit are either stainless steel or zinc-coated and they are high quality with no thread issues on any of them. The kit includes a wrench for the nuts but you will need a Philips screwdriver to assemble.
Assembly is simple and takes less time than it takes to peel the plastic from the panels. There are four braces for this model to maintain the structural integrity after it is filled with dirt, tow top braces and two bottom braces. They are female threaded rods that attach to the screws in place of nuts. They are easy to install. Once assembled this unit is very rigid and feels durable and high quality. There is a nice aluminum reinforced edge guard for the top edge that is easy to install. It presses into place with a thumb. At the overlaps make sure that both sheets are inside the notch in the edging.
It is easy for one person to build and to move this around the yard. It is light enough to carry anywhere while being rigid enough to hold together.
This is a nice product and we will consider buying more as we expand our garden area.
