Wrong battery supply. It's about 2 pumps, none of them worked. Completely useless. No leaflet with information. Money wasted.

I haven't managed to make it work, even though it sounds like it works, it doesn't fit properly into the oil can and it doesn't draw the oil

Unfortunately, the pump retains oil... no matter how much you empty it... while it easily removes the oil... it retains oil in the pump and if you don't secure it somewhere because there is no cap, it leaks

Very good, it helps me to transfer oil from a large concrete to a small one. I bought 2 because I needed to open them and make a conversion to the motor's rubber that gives motion to the lower axis, as this was the only problem they both had. If you don't fix this conversion with your hands, it will only last a few days and the motor will turn without the axis turning

Purchased for 7€ + 3€ for the batteries. I tested it directly by pumping water from a full 4-liter jug into another empty one at the same height. Although the empty jug overflowed as it seems it couldn't hold the same amount of water, the pump took 45" to fill it. I repeated the test again and got the same times, always making sure that the liquid outlet was not below the water. It is used for pumping gasoline, not recommended for pumping oil. Attention: the evaluation refers to the product shown in photos 2, 3, 4.

For pumping water and fuel, it's great.... I've had it for a month and it's superb!!! I will come back later for a reassessment

Comfortable to use, the flow is a bit slow. Personally, I have bought it for changing the water in my aquarium.

It is not an oil pump as it claims, it is a water pump for large containers. It does not fit the 17kg oil tin and the pumping is very, very slow. The worst.

I got it for kerosene. It does what it says correctly. I use it with rechargeable batteries.
Update After a month of use, it stopped working.

I'm sorry I bought it. STAY AWAY. Ten to fifteen minutes to fill a ten-liter container with oil. And that's only if the container you're transferring from is full or the level is high. When the level goes down, it DOES NOT transfer anything at all. The ten euros along with the batteries are a waste.

Initially, it does not fit in a 17-liter tin of oil due to the long length of the hose. Also, although it appears to be of higher quality compared to other cheaper pumps, this is not the case. The on/off button broke after a year and essentially ten uses, and the pump ended up in the trash.

For the money, it works perfectly and does exactly what you need. You hold it so that it doesn't touch the bottom of the pan and effortlessly fill your oil bottles. Sometimes it made contact in the off position, resulting in it not stopping unless I removed the batteries, but it's a minor inconvenience for using it once every two months. 8/10

It does not fit on tin oil cans. It is for large bottles of bottled water. However, it does remove the oil. The one they sent me was slightly different from the photo in terms of the flow spout. It did not have the flexible tube but a plastic fixed one, perpendicular to the body of the pump.
