So far so good! I can't attest to it's battery life but am hitting the road soon with this and maybe will add comments on it. It took a few hours to charge up when I received it. It fit on my 3 gallon stackable jug with the right cap it needs to function that I purchased along with this since my jug came with a screw on cap. I purchased a cheap set of 5 blue caps from Amazon for maybe $7 or $8. The tub came out of the packaging folded together and perfectly opened up without any need to fix or mess with it. I love that it is ready to use like that and storing it again doesn't impact the tube either. The water flow is steady, quick, and motor sound doesn't seem too loud or bothersome. Thank you!I saw a review on YouTube, SUVring and he was pleased with its performance. So am I although I've only a short history with it. It functions as it claims and the volume modes are pretty accurate. I installed mine on 4 gal Reliance jugs. I had a spare cap so I permanently mounted it to that. I had no idea how convenient it would be! For the price point it's a huge Win! I used hot glue with both connections. I cannibalize the spare cap and simply cut the length of spout to correct depth. So easy a caveman can do it...?It does a great job of fiiling containers quickly, much faster than our refrigerator dispenser.Pumps the smaller stream so it takes a little longer to feel things. Has precise measurement. Does not have any grip on the inside like manual hand pumps so is only held in place by gravity.Works greatReally happy with my purchase! Fits well on my 5 gallon jug and pumps out water quickly. Have sent the link to several people who wanted to purchase one also. Lasts a long time on each charge. I like the preset fill buttons. Only thing I would change would maybe be to have to preset fill buttons be in ounces instead of liters. I did the math and converted them and wrote the converted ounce amounts on the side of the pump. Very happy with my purchase!Haven’t had it that long but use it daily.You a better than the hand pump I’ve been using.I wish the button would stop poring water when the button is release, instead we have to click the button again. I forgot once and was holding it down thinking it would stop when I release. I was wrong and spilled water. Besides working good it’s just loud.Satisfied.Easy to use.Water flow has the right amount of speed.cette petite merveille fonctionne super bien, très surprise pour la grosseur et la durée de la batterie pas négligeable non plus fait un 18 litres, le tube flexible prend l'eau jusqu'au fond, bonne achatWe love this product :) it is light weight, easy to you and keeps an excellent charge.Arrived today, recharged it and it works great! Very Happy with purchase! Fast shipping too :) Thank You!Pour pomper l’eau de bouteilles de 18 litres. L’adaptateur devrait être fourni avec la pompe.Exceeded expectations. Wish I bought this 5 years ago.
