I actually have this in my sump even though it says not to do that, but it works fine.  Just make sure it stays submerged and the temp sensor is in the same water (ie in the sump).  For a 30-gal, I keep it at 80 and it keeps my main tank at about 78.

The deluxe wall mount skimmer was simple enough to assemble although the instructions did not mention what to do with the flow reducer.  I am mechanically inclined and figured out to use it on the unused outlet if your pool has two outlets so that the outlet you attach the skimmer will have enough suction to pull water into it. The skimmer does work pretty good as long as you make sure it is level with the surface of the water.  I do wish that the bracket that it came with had a little more range of adjustment because it is bottomed out and the bucket falls out occasionally allowing leaves to get into the bottom of the skimmer clogging to outlet.

First, it works. It works just the way it was intended to work.

What they do not tell you is that it is an air pump, not a water pump. It builds up pressure in the bottle you attach it to (a plastic bottle will bulge a little), and lets the air out when you release the pump plunger. I am not sure I would have bought it had I known that. But it does work reliably. The one caveat is that one must really push hard on the down tube (the one the water comes up in) or it will fall off during switching water bottles. Not a big deal, just letting you know.

Personally, I prefer a water pump to an air pump. The amount of air compression involved in a nearly empty bottle is significant.

Its not bad for the price, It works well but its important to seal the low rail edges properly or the floor will be flood. Seems obvious but its not, it reqy&iquest;uires a good paste of silicon inside to avoid the water to leak out.

I tested this product before hand by lutting a tissue in it and submersing it for 10 minutes underwater. I'll post pics so you can see that its completely dry. Any specs of water on the tissue would be on the sides only because I didn't fully dry off the outside before pulling it out. This little bit of water wouldn't ruin an electronic anyways. It works great but it is cheap so don't expect it to last forever. A friend who bought the same thing said the clip broke after a few months. I'd personally pay the $7 every few months just because It's so effective.

The only negative I see is that the temperature gauge on top is hard to read while submerged. Other than that they appear to work fine and are keeping the water at the temperature desired.

Works okay. Has to be just right to work properly. If water levels go up or down, you have to adjust the skimmer. Have to take it out of the pool pretty fast to avoid dumping stuff out of it.

It works  great the only you thing might want want to do is make sure the seams are water tight. but not a problem.

its okay. At times you have to wait about then minutes when you turn it on otherwise  it leaks the water.

It works fine , but at a 4 ft lift doesn't have the power it should . That said been in the water for a couple of months still pumping.

It seems to be working as advertised, as we have been using it for about a month now.  I have noted that it is fairly sensitive to water level, so keep that in mind.

It works well, but if you take it in the water it gets inside. I would recommend pulling it apart afterwards just to let it air dry. Other than that it works well and is very light weight.

For a generic it works just fine, it proved to be waterproof as stated. I was a little sceptical at first because the sealing clamp looked as if it left space to allow some seeping but tested perfectly. It actually trapped air in it and when sealed it's comparable to a sealed bag of chips etc. I use this when paddle boarding and even proves to work fine when I occasionally swim after and fully submerged, but this is ONLY at surface, I wouldn't recommend or able to speak about taking this diving if that's what you'll do.
  The only down side to this product is the shoelace like material which encased the headphone wires as they become heavier when soaked and puts a strain on them staying in your ears when in the water as they are only wedged in your ear. Also the headphone wires DO NOT have a built in microphone so it isn't ideal for calls. The arm band is too small for my arm I wish it had a little more to adjust!  Other than the last 3 mentioned, I would give this a 5th star.

this works great floating next to you or in the canoe next to you. It's not way loud, but it's better than headphones. You can hold it underwater. It's safe.

Despite lower reviews i read before taking a chance on this,  if its actually installed correctly, it works rather well. Ive had it for months and not once has it leaked a drop any where on it.

It works o.k. Need to not squeeze too  hard or you'll get too much of a blob of white liquid on your mistake. Need to have patience to let it dry before trying to write over it.

We lost the stopper for our kitchen sink, so I bought this, thinking it would help in a pinch.  If you position it correctly, it's great. It really holds the water in. But, you have to be careful not to knock it out of place, or all of the water will drain out of the sink.  I like that it's small and flat, so it can be easily stored, and once it's placed correctly, it does the job.
