We just put together our Chumbly Cantilever Umbrella and it's exactly what we needed. It is very well made and relatively easy to put together, despite the limited instructions. However, we did run into a couple of problems which were our own fault, but might serve as advice for someone. When we had it all put together we couldn't open the umbrella...because we had forgotten to remove the packing material inside the umbrella, near the top, which was holding it together. You must look inside the collapsed umbrella before you mount it! Also, we couldn't get the umbrella to swivel until I realized that I had confused the bolts I and H. One set is longer and when I put those in through item C they were too long and blocked the gear from turning. Once I exchanged bolts (one at a time so I didn't have to take anything apart), the longer ones went in first and the shorter ones went into C, everything worked perfectly.
