There is nothing wrong with the product itself. However, the description in the catalog is a bit misleading, because the level indicator for fuel gauge also contains this. In case of doubt, you will therefore acquire two fueling stations.

Size of probes are short for waste tank in vertical position.
The waste-holding tank is empty, but it is shown in full because something that looks like it has got caught. Then it has to be rinsed extensively. Not the final solution!
Unfortunately, the electrodes are way too short for many tank sizes. Therefore only a star because I had to laboriously calculate and extend the electrodes. I have already written how it works.
Maybe it can work with an electric toilet (with grinding) but after the first use and whatever waves, this gauge indicates full while it is empty. I disassembled to clean, and the next navigation is 'full' again. For me, it is not compatible with a black water tank. Too many particles which can cross the contacts and give a bad level. I'm going to change to a digital gauge.
