I am satisfied with this pump that currently doing its job. The flow rate is more than enough for a mini-terrace pool (there is at least !!!) and more effects are possible ... of course it takes a fairly straightforward sun. Now we have to see what happens over time to test the robustness of this small pump (use 1 week). The only catch is that I would have liked to buy a second for circulating water between two other mini-basins but just increase the price ... damage.
