I ordered two six packs and they arrived in a timely manner. There was some minor damage to two pieces, but nothing that affected the usefulness. So far, I have only dry fitted all 40' of drain, but it looks really nice. They seem very heavy duty (compared to Home Depot stuff). Even dry fitted in the cement cut trench they have been effective with the last rain. The drains will be running out into the yard about 60' and then exit through a installed opening at ground level. The installed drain will rest on a sand bed, and the fit will be sealed in with crack filler.
