You get 4 pump, two for a more vertical position, and two for horizontal.I used one of these to pump away about 2 inches of water on my balcony.Hooked it up to a power bank used for my phone, and it took less than an hour for it to only leave a couple of milimeters of water. This could be easily mopped up.

Alles in Ordnung immer wieder.

J'enlève mes 5 étoiles. Les 4 pompes ont cessé de fonctionner l'une après l'autre, après seulement quelques utilisations chacune. je m'en servais juste ponctuellement pour transvaser des seaux ou bidons sans avoir à les porter. Je suis passée de très contente à très déçue.

prodotto conforme, però non durano molto, circa una ventina di giorni.

Let's start from the beginning. The pumps are quite powerful, and I am satisfied with their flow. Unfortunately, that's the only positive thing about them. The pumps are extremely noisy, resulting in a constant humming sound that often becomes irritating. At night, there’s no way to avoid turning the pumps off.The worst part, however, is that the pumps frequently stop working for no apparent reason. No matter how many times you try to restart them, nothing happens. The pump must be removed from the water, and the impeller must be manually restarted. And this happens often.Initially, I thought something from the aquarium elements was stuck in the impeller, so I tested them in a clean water tank. Unfortunately, the same issue occurred there. The pumps have no way to open the impeller for cleaning if needed, so you have to resort to using toothpicks and small screwdrivers to make the impeller rotate.In my personal opinion, they are not worth the money. With the same amount, you might not be able to buy four pumps, but you can certainly buy two much more reliable ones, as I eventually did.

4 mini pompe con attacco usb , per il prezzo pagato vanno più che bene , gli stessi prodotti si trovano a corca 2 euro l'uno dalla cina , ma se non avete voglia di aspettare per 4/5 euro in più ci sono queste.In verità a me ne serviva solo una per progetto per il mio acquario, pero ho preferito prenderne in più per avere scorta.
