Review on 🔋 TERA PUMP TRHA03 Battery Powered Water, Diesel, Gas Transfer Pump with Leak Prevention System (Auto Stop) and Buzzer, 2 AA Batteries (Not Included) - Efficiently Drain Sinks, Tubs, and More at 9 Liters/Min by Kyle Smernes

Everything works as advertised. It pumps liquid very quickly and smoothly. It stops as soon as the fill level is reached. However, I have found a few negatives or downsides. (1) The battery cover is too loose and will slip and fall when you hold the pump. I solved this problem by sealing it with tape. (2) The suction end of the pump is wide and it was very tight in the antifreeze bottle opening, I really had to use some force to get it in the bottle. So if you want to pour liquid from a small openable bottle, you will encounter a problem. There should be no problems with the gas bottle. (3) After pouring the liquid, liquid will remain in the tube and will not come out even if you leave the pump on for a while to pump out. I don't think keeping liquid in the reservoir hose is a good idea. My solution was to fill a container with clean water and run the clean water through a pump and hose and then store it.
