Quite good, with a few limitations ...

After unpacking you should stretch the hose.
Either with a hair dryer or long hanging on the ceiling.
(If yes logical that you must send rolled up the hose), not so here
Deduction of points as in some other reviews.
I've tested the whole only with a bucket of water, took a bit to it
has geklppt.

Negatives:
-I Think the tube diameter is too large, whoever pumping large amounts of water
who wants to be an electric pump should get or there must be 2 variants.

I try in the near future times leerzupumpen a car tank, let's see if it works. Until then, 4 stars, good value for super.
