There are two unterscheidlich curved fittings for 100 mm and (I think 75 mm) supplied pipes. The remaining parts are mostly provided with grooves must therefore be put together in a precisely defined position.
Knowing this, is ever gained much.
The (included drills) has eased with me immediately and I had to tighten the screw with which it is mounted in the drill crown.
Is that part then once installed, there is nothing to complain about, the accumulated rainfall is super. In heavy rain a really full beam comes out of the 30 mm hose and in dim light rain is still collected, although of course no major amounts can be lopped off.
Incidentally, an adapter is supplied, with the only 30 cm long, enclosed hose connection may be laughed changes easily (there are in any better stocked hardware store in different colors. I have a transparent
chosen because it then can easily see if the water flows).
So, great product with very poor unconverted assembly instructions. Perhaps the manufacturer should think about a bundled version of paper for folding because of the space on the packaging bag is just very limited.
