This pump is very easy to install. I put it on 5 liter water bottles. When the water bottle is full, the pump quickly ejects a good stream of water. When the water level is very low, more pumps are needed to pump the water. Not a big problem, just physics. I can fill a liter jar in about 10 seconds if the water level is high. It takes 15 to 20 seconds to fill a liter jar when the water level is about 1/4. Good deal at $10 and no batteries or charging.
