Too bad 15 1

I bought this product because in the picture it is very similar to mine
(I have a hung WC ground / ground SIAMP)
In fact the central tube is shorter than 1 cm, it forces a decrease
volume of water in the tank or it constantly flows through the tube.

But the worst is that one of two levers was mounted perpendicular
to another. I turn it a quarter turn to take up his position
as in the photo and the surprise it does not take up and falls
constantly in the tank, what a coincidence!

To quickly WC in service again I had to replace the
defective part was using the old mechanism instead of returning all

I'm really disappointed with my purchase because of this hidden problem voluntarily
by the manufacturer, a shame !!!
