I love everything about these beds. The minimal design, sturdy construction, and the non-chemical leaching coating. I plan on having at least 10 of these in my garden. But honestly the assembly takes 2 to 4 hours not 40 minutes. Each panel has a clear sticker on either side of it, it can be difficult, taxing, and slow to remove, just think if you spend five minutes on each panel and there are 20 panels, it can take a while! I wish they would come up with another way to package and protect the panels. If they fix that this would be a completely enjoyable experience to assemble.
