Sealing, but not good quality

See the bottle holder on the image of higher quality than in reality. Aluminium is only the holding rod for the bottle. The rest, including the clamp are cheap plastic with silver paint. This makes the whole thing looks a bit "cheap" and is certainly not a "standard catering".

To function: Overnight everything was tight. Longer I could not test. However, it seems to work :-) Large drawback: It is so cumbersome. One need right power to some "pin" to. In the cheap bracket but this is a big drawback: All bends and you're afraid that breaks something.

Conclusion: Wobbly, not really quality crafted Batcher which works but is not really pleasant to use.
