TIAKI Railing Clamp for Telescopic Poles

The idea is good, and I ordered 2+2 units straight away since I'm not allowed to drill holes on my balcony. Unfortunately, one of the poles was missing one of the lower end caps. Also, I was a bit disappointed with the overall quality and how well the parts fit together. For the price, I expected much more. I regret buying it.

When it's windy or the temperature changes, the poles fall over. So they're useless.

I just can’t get this to work at all. It doesn’t feel like it can be tightened properly between the ceiling and the floor, so it feels really unstable. Plus, it’s very difficult to tighten it and keep the net in place at the same time. Managed to set it up once and will probably give it another go soon. But I’ll most likely end up finding another solution to put up the net it’s meant for.
