Ordered two sets for my home theater setup. These things are heavier than I thought they'd be, which is good. Assembly and speaker mounting was extremely easy, including the fishing of speaker wire through the post. However, upon inspecting the parts on the first set, one of the couplers for the height adjustment was broken. The next day I called and sent photos of the damaged part. Now, I only needed one part to be replaced the one set. Perlesmith sent me a complete new set and I received it less than two days later. That's awesome!
