Kleinmetall Roadmaster Deluxe Dog Safety Barrier

I bought this set for my car boot, but I’m extremely disappointed. The quality is poor: the extendable telescopic rods are far too loose, wobble a lot and even fall out of their guides completely at the slightest touch or vibration. There’s no way you could safely secure a dog or any cargo with this. Even the manufacturer advises against using this unstable solution for larger dogs. For this price, I expected it to be much sturdier.
