The workmanship is very good, no burr or other defects. Only in the threading of the cable (came with us in a few seconds) was apparently in the pipes "lubricant" or so inside, but I did not feel as bad now. Otherwise, virtually every component is here made of metal, therefore very robust.
Assembly:
After about 30 minutes were all 4 (we bought 4) mounted stand. The assembly instructions was a little spotty. There come various mounting plates in question, then you have to decide on your preferred. Our speakers weigh about 1.7 kg each, and it keeps everything fine. I think speakers up to 2.5 kg can be mounted in more I would be careful and would the altitude (hence how far the telescope tube is extended) consider.
