Stop is not equal to Stop

The product is cheap and easy to assemble. Unfortunately, the shipping costs are for such a favorable part then incredibly high - nearly three times the price of products, but with the need to live and will also previously noted.
Anyway, I've got a leaky shower - the installer has been to me a new faucet to 200, - built Euro - but nothing helped - now have the old ones inside - the installer is perplexed.

Thought to myself, so if I can leave the Tropferei not at the root (fitting), then "stop" I water just later and have me first once bought a new shower head with shower stop - but was nothing to stop, it drips still - thought me: Ok cheaper showerhead.

Now additionally bought this shower Stop - unfortunately but again nothing with no dripping shower. Was not until the package inserts: Due to high pressure in the pipes of the shower stop must always leave a little water.

And that's what bothers me here because this article is not really likely to stop hot shower, but Wasserdurchflussverringerer and I would have liked this part is not ordered and paid in addition still almost three times as much shipping for nothing and again nothing.

Conclusion: Shower Stop is a misnomer!
