This pump worked very well for about 15 minutes, then it sprung a leak and was of no more value.

It was a nice pump while it lasted.  Gets very hot, but I guess that's how it chooses to kill itself.  Loud too.  Spinal Tap would be envious.

Works well, once I was past the initial splash of water from the nozzle. The capacity was less than I would have liked... lasted only 7 minutes as you advertised.  But it will work well for travel.

This pump ran for one week before it died. It was only pushing water 18" high
which is much leass than it is rated to handle.

I bough this pump at the end of September 2015. Unfortunately I didn't try to use it until after the return policy expired. The first five minutes, it seemed to work fine... then it stopped all together. I was only using two feet of hosing, but even with the hose removed nothing comes out of the top. Requesting vendor support.

I was using this pump to recirculate during mashing. It burned out after 5 batches. Apparently the lifespan of this pump is 5 hours of run time.

I used this pump immediately after I received it. It worked as advertised and I was happy.  I mounted it om the frame beneath the bracket for the water bottle and it fit as advertised. What I was dissatisfied with is that on my SECOND ride after mounting the pump, it fell off the mounting bracket and I didn't notice. Now I have to Spend another $11 (plus shipping) to replace it. I plan on buying another, I need a mini pump and this one worked well, but I will carry the new pump in my backpack or in a toolbag mounted under the seat.

installed to replace failed mechanical pump on Kubota x900 diesel.  Lasted about six weeks with about 2 hours a day or less usage.  I replaced it with another,  we will see how it does.  Replacement failed in about the same amount of service.

My daughter bought one of these last night and it is a cool idea for crafts.  It was easy to use and worked well..... for about 10 minutes, then the pump died completely.  Fresh batteries were no help and in the end we returned it.

We bought this pump to replace the one that our intex 12' pool came with. We had it 3 days before it stopped working. There was a "pop" and now it's dead. There aren't any replacement parts to fix it either which leaves us to buy the same exact pump or spend even more money on a different one. The 8-10 hours of use we got out of it were great, there was a very obvious difference between this pump and the one the pool came with. With that being said, I would recommend just spending the extra money on a better pump.

We had this for 10 months. The pump started sticking a few months after we received it. Then it stopped pumping after 10 months of normal use. We used it with Dr Bronner's liquid soap. Get a different pump. This one will annoy you.

What a deal. Drained my pond in 15 minutes. In the past took almost a hour and a half. Old pump cost me twice as much. Only problem was the male connecting sleeve. Hose called for a female connecter.

I used it to pump out the water in the small reservoir in the yard, but after 4 hours the pump lost ability to maintain fluid traction.........
Will try another product in the future.

Works great.  Takes 6-8min for each of my sups to get to 15psi.  It didn't shut off one time and went to 18psi before I caught it.  Now I'm cautious about it and watch the gauge every time I pump up.

---===UPDATE===---
After about 10 uses the pump no longers stops at the desired psi.  As a matter of fact, it doesn't stop at all.  I set it to a lower pressure setting (5psi) and it still did not stop when it had reached 15psi.  I'm glad I continued to monitor the pump as it ran as it could have ruined my $1400 ISUP.  To further the issue, the OFF button stopped working too.  I had to disconnect the power supply to stop the pump.  I had hoped this would be the all-in-one solution for pumping up my ISUPs but I will have to keep on looking. (I've heard of some bad stories with the other two offerings from this online company beginning with AMA and ending with ZON.  To recap, it worked the first few times and stopped working after a few more times.  I buy a airhead products and I like them all.  This one is just not tried and tested yet.  Needless to say, I will be requesting a return on this item.

This was part of the AquaTop MR-30 GFO reactor kit that I purchased.  It last FIVE (5) MINUTES only!!!!!!!  Now I'm stuck trying to find another pump.

When I first got it, it worked well. However, within 45 days it started rattling when I turned it on... past the time that I could return it to Amazon. I would expect a pump to last longer than 45 days.

I really like this pump when I installed it in my outdoor aquarium. The flow rate was incredible. I bought this item on 05/31/2017, received it on 06/02/2017. A little after two months I started having issues with the pump, it stopped pumping water. In the weeks before it died out, I noticed that the flow rate had slowed down and sometimes after cleaning the pump won't start right after you plug it in the outlet (had to adjust the impeller cover to get it to work). I checked the housing, impeller, sponge filter, hoses for any possible issues. There didn't seemed to be any visible issues like a motor burn out or clogs. The pump just stopped working after 9 weeks in service. I'm quite disappointed with the durability of the item and customer service. I tried contact Amazon and the seller, but couldn't since it was passed the 30 day return policy.
