Review on Hanperal DC 12V 5L Transfer Pump: Efficient Oil Fluid Scavenging & Suction Vacuum by Christopher Millet

I used this to drain the transmission oil before changing the filter and it took just over an hour to pump out 2.25 litres, I expect there is plenty more left in the sump. I'm not sure if the pump stopped working or if the machine ran out of pumping oil. It has ridiculously short power cords that look extremely flimsy. And the pump hoses are ridiculously short, too. And please someone post the correct diagram of all the tubes and where they all go. Mine came with all the clear tubes separate from everything else. Makes for a difficult experience. These improvements need to be reviewed before I can approve them.
