Good pump, bad suction cups.

Good pump.
Has plenty of hook up options and uses.
Was using inside a fish tank going into an external filter.

This pump works well and moves a lot of water.
Can be used as in internal or external pump.

I have since removed it from the tank as I have a different set up but I still use it to help when I need to drain the tank.

The only real con I have is that the suction cups are bad.
They do not stick very well and do not stay attached to the unit well either.

Overall it is a good powerful pump.

This is a nice little pump.  Have used it for bicycle, motorcycle, vehicle tires.  However it quit after I have used it for about 6 months.  The fused power source was fine, however discovered that the fuse in the pump power adapter blew during last use.  Should be easily replaceable, but the heat from the overheated fuse had fused the power adapter plastic together and the blown fuse could not be removed.  Had to dismantle the power adapter and replace the blown fuse with a much stronger fuse material.  Pump now runs again and does its job.  Would have replaced the pump, but most replacement pumps have the same type power adapter.  Poor design and poorly tested by vendors.  Buy it if you need it, but be prepared for power adapter repair to keep it working.

These are good pumps.  I've been using several of them on my boat for shower sumps and bilge pumps.  It's nice to not have filters to clean.  So far there have been no problems in about a year of everyday use.  Right now I have one that is working hard as I have a leak.  It comes on every 1/2 hour for a couple of minutes.  These pumps can be changed so the inlet and outlet are pointing either direction, and also the motor can be flipped, so it can be set up 4 ways.  Minus a star because the little panel you remove to do this breaks before it releases.  The first one broke without any help.  After following the directions exactly I broke the second one.  Cheap crappy plastic.  It's too bad because the design is really good, but they cut corners (China) just to save a few cents on the plastic housing and cover.  My pumps work well, even with the tape holding the covers on.  One of the pumps came with a broken foot.  Yup, cheap plastic.  Again.  No pride of product.

Does the job but the suction cups aren't deep enough to suction to anything and slippage is a real fear for me. Its ok as long as you are very aware of the way you standing in the tub.

Work well, minus the fact that the suction cups don't hold - so they kept falling off, dropping the sensor from where I wanted it. I ended up removing the suction cups, handing the thermometer from a nail on the wall and taping the line to our tank, to ensure the sensor read from where I wanted it too.

The suction cups aren't really that strong.  Every time I turn the water on it washes this thing to the other end of the tub which is a little annoying and makes me question how well it functions but, it's good enough for now.

Works pretty good. I'm running the 1000 gallon inter pump and does the job. I was expecting massive amounts of suction, but I believe the tube is too long to provide that. All in all the suction it does provide gets the job done.

We have a shower that's one of those fiberglass insert dealy-hoos. Not what I would have chosen when remodeling but hey, it wasn't my house then, so I wanted a real soap dish to keep the soap from sliding off the stupid little shelf. Also I wanted one that drains well so that the soap wouldn't sit there and liquify in water, which drives me nuts and I believe halves the life of a bar.

The actual soap dish is fine; should be sturdy and last quite a while even with water exposure. However, the suction cups seem to be pretty bad. I don't really like how they're attached, since they're pretty loose, but the real problem came because they are cheap plastic, and Amazon's shipping area shrink wrapped the whole thing to another item I ordered. Unfortunately, the heat from the shrink gun warped the cups. So this is partly a problem with the warehouse people not considering this possibility, and partly low quality parts.

I got it stuck on the wall with some oil on the cups, but I don't know if it will stay long term. The good news is I should be able to replace them pretty easily if I need to. Just annoying to have it arrived damaged.

The net is huge and I had to put this at the back of my bath tub.  (My tub is average size, not over-sized.)  While I think the suction cups are awesome.  The size of the net makes it unwieldy....I had to angle it up awkwardly to keep the toys from spilling into the tub.  It does hot a lot, but the front net is narrow and low, so unless you angle the net upward, the heavier toys hang toward the front of the net and tumble out.  It's okay and I will use it until it falls apart.  I'll save the suction cups because they come separately and can be used to hang puffs or mirrors after the net falls apart (and they always do)/

The suction cups do not hold well on the bathtub ended up putting it on the wall after I bought different scution cups for it.

The suction cups don't want to stay "stuck" to to SUP. We still have to use small bungee cords.

Good pump but broke after a few uses. Air comes out the bottom so I have to block it with my hands. All in all it was good for the price.

The holder holds the phone nicely, but the suction cup doesn't work very well, even though it uses both suction and sticky. I'm using it to aim a phone converted to a security camera and twice it has lost suction and fallen off our window while we were gone. I'll figure out a new way to mount it.

Good for the price, could have a stronger pump.

Great caddy.  Forget about the suction cups though.  they are extremely cheap and won't hold for longer than minutes.
To use you will need to drill holes through the caddy and into whatever you are attaching it to.
I did not want to do this to my boat which is why I bought this with the 3 suction cups.
At least it was cheap...it's in the garbage now.

This item looked so good - as I wanted something to allow drainage for all the toys!  Got it together, but the suction cups just aren't strong enough and keep coming off, then it falls apart....:(:(  I sent it to GoodWill and am back to my old plastic basket.

This is a nice little pump, much scaled down from what I previously used on my 80 gal indoor pond.  I like that it is very quiet (I only hear the water, which is a very gentle sound.  I do wish it had a real filter on the input, but we'll see how that goes.  My main complaint about this pump is its lack of stability.  Despite the suction cups, due to the pump's small size, after a while the flow itself will result in tipping the pump forwards, sending the fountain spray elsewhere than planned.  Bracing it with rocks may help.  If not I'll have to adapt it to a larger base.  If it came with a larger base or a prefilter extending from the inlet, this wouldn't be an issue.  Probably wouldn't be a problem in an aquarium, where you could position it into a corner or at least put the back against a wall.
