Totally satisfied - hard working small pump
I am seriously impressed with this.My backpack pump, which is of good quality but manual, blew the plastic piston on the pump and a new one was almost 35$!? I decided to look into adding a pump that could provide the output that the pumps wand could handle.This pump did the work! And whats more is that I didnt use the backback sprayer but a 55 gallon plastic drum I bought on marketplace. I attached a long sprayer feeding hose to it and put that down the drum.For power I pull this drum on an old cart I have (can only fill about 40 gallons before it starts tipping). I took a partial electrical cord and attachted one side to a nice ip68 switch and to the pump. then the other put small jumper clamps on so I could put it to my mowers battery.the tank now also has drip irrigation that I can turn on and passively pour out water. But I can also spot spray plants if I want or even strap the hose up top, lock it "on", and drive around my 6 acres spraying Humic and Fulvic acid water everywhere to improve the soil!The little pump has now run 40 gallons almost non stop in one sitting and ive probably sprayed another 50 gallons through it without a single issue.it has a feature where it gets to a specified internal pressure and shuts down until you drop that pressure. If it seems to be running continuously I recommend flowing it and its likely that there is just air in the lines not compressing like water causing this.Id highly recommend this if you want to push water in small tubing. It has a lot of nice functionality and runs easily off a 12v battery using off the shelp bits and bobs.

Great high power pump for misting.
Used it for misters and it works great, runs two mister sets and automatically shuts off once the pressure gets too high. This is great. I'd buy this again.

Good gadget
Bought to supply RO system with water under pressure during disasters when house water is off. Pumps like crazy! At 3 Amps and 12 Volts this doesn't sound very powerful but it really pumps. With a small LiFePO4 battery this will make a portable water-stealing tool for preppers like me!

Pump ok but pressure switch not so much
The pump works well but the pressure switch is really bad. According to the specs, the pump is set to turn off at 80psi and turn back on at 35-40psi, which is exactly what I was looking for. Unfortunately, when the pump reaches around 80-85psi the switch cycles like mad for at least 30-45 seconds befor it shuts off. I could probably live with that, assuming it might break in and smooth out with some use. The really bad part is that it turns back on at 75psi and not 40psi like it is supposed to. This is really bad for my situation since I am using a pressure accumulator. This pump might be ok for use with an on-off faucet application but not for anything else.Update - I am a retired engineer from the pump business, so I was able to make some modifications to the pressure switch to get it to work as it was supposed to. With my new 3D printed parts, the pump shuts off cleanly at 80psi and back on at 40 psi. This opens up a whole new range of possibilities for this pump now. The switch should last a lot longer too by not rapidly arcing the micro switch every time it tries to shut off.

Both pumps (1.0 GPM) working GREAT for 2nd season!
The 1 GPM pump is EXCELLENT, especially at the price point around $20! I haven't metered the pressure, but the advertised 80 psi was noticably more powerful than my 60 psi HighFlo, and had to be turned down! It starts and stops smoothly. I bought two of them to power my 3 gallon pump up sprayers, so I didn't mind that the motor was open to the elements. If you are going to mount this on a larger sprayer that could get splashed or rained on, you may want the enclosed 1.2 GPM pump. Both pumps are working fine for the second season.

Noisy like a mare in heat
Want to wake up you neighbors or wild life, this is your go to pump. Added a drinking water only tank to my off grid X22 and didn’t need 3 gpm. My install used black foam panel, wood and another foam panel, still made a major racket. I then wrapped it in a plastic bag, covered it with a box and sprayed foam into the box for sound proofing. Still was noisier than a mare in heat.

Fantastic Pump
this little pump is great. it shuts off when it gets to pressure which i like and it can really move water for how small it is. its a little loud but as i only use it for camp sink i dont mind. but if you have a small van or boat and it will be mounted inside its something to consider.
