The Slim S10 Power Filter's motor is submerged in the tank for a quiet operation and an easy start-up since no priming is required.

The s15 works great for all my needs. I can shove different filter media, the flow is adjustable, and it was on sale for almost $9!
HOW I CUSTOMIZED THE FILTER
I decided to use two of the filter packs that came with the filter and slide them into one space.
The sponge that comes with the filter wasn't fine enough for me so I took it off and used a little bag with poly-fil to mechanically filter the water. I placed this in a small section under the intake and tied the bag over the intake.
I then used the two empty sections for biological filtration. I added some pot scrubbers and some k1. I used a red pot scrubber and k1 from my old filter and added some new ones also. I tried different methods of inserting them too. Using a media bag or even stockings allows the media to stay in place but you could also just stuff the pot scrubber on top of the k1 to stop it from spilling out.
All in all I think this is a great filter and I love the price. I would even pay more for this!
I bought this filter to use on my 10 gallon that houses 1 solitary African Cichlid. Before her I had varying inhabitants including a crayfish, a fancy goldfish, and guppies. This filter kept the water quality good for everyone, but the mechanical filtration is not my favorite. In this particular filter the foam slides over the inlet inside the water. This makes it inconvenient for me as the lid my particular tank comes with makes taking out the the inlet tube that goes in the tank water more difficult.
To go further into filtration I will note that there are two areas designated for Marina brand cartridges in the body of the filter. The cartridges you can get vary, but none of them are filled with that much filtration media. Also, if you do not use cartridges in both compartments, the water will not be forced through just one cartridge. Water will be able to easily bypass around. I personally do not have two cartridges, but instead one carbon cartridge and a full bag of biological media. My water in my 10 gallon always tests great with that combo. The water does have many particles floating around, but the water is crystal clear.
If you are looking to use this for a more fragile fish such as a betta, I would think it would be perfect. It is incredibly compact and quiet and the water that flows out is a gentle current. Since the overflow is fairly deep it will most likely reach the top of the water level in your tank and make no splashing or noise. This might be a fault for some people as some like to have the water splash as it flows out to add more air to the water, so something to take note of. If you want splash action your water level will need to be almost 2" below the top of the tank.
My biggest gripe with this filter is that the foam is inside the water and the pump is as well. The pump is inside the water and so it might be an eye sore for people who don't want to see a big black box in there. Also, the cord that powers the pump must also go into the water and this can be a potential area for a leak. If you have, say, a bubbler below the pump that is making the surface of the water splash onto the cord, it will eventually build up and start to drip down the cord and create a siphon action out of your tank. You should always have a drip loop on all aquarium electronics, but I had a huge puddle behind my tank due to this (learn from my mistakes!). I understand the the compact size of the filter can be achieved due to the fact that the pump is in the water, but I would prefer if the cord had a hook or something to keep it off the side of the tank to avoid this issue.
On my larger tanks I prefer the Fluval C4 power filter as I can place foam, carbon, and biological media in the body of the filter that I can then lift out using the built in compartments. For the smaller tank though, I am very please with the Marina's performance, compact size, quietness, and price. I have been running it 24/7 for 3.5 years and it is doing fine.
It seems to be working pretty well, the intake tube is very close to the out flow though, so if the tube touches the outflow, it hums quite a bit louder. Also, I have bettas in the tank, so even with the outflow being at it's lowest setting, I still felt like it pushed my betta around too much if he was right near the outflow. So I just used a strip of plastic from a water bottle and used a rubber band to secure it on as a baffle to lessen the current. Works pretty well. Overall I'm happy with it, and it's super easy to customize your favorite media into. It's my first HOB filter, and I'm liking it for the price.
I own about 3 of these Power filters, and ordered 3 more in the last two months. They are really great when the plastic piece (covered by the sponge) connects tightly to the motor. When it fits tightly, it runs flawlessly. Out of 6 sets, the first three sets were perfect. The first three sets were a S10 and two S15. Now the 4th set was a S15, and the plastic piece didn't fit tightly to the motor. While in use, the piece disconnected, and the plastic piece and foam were floating. The motor bottom had the exposed hole. My goldfish are big so they didn't sustain any injuries. My 5th set (S15) was fine, but my 6th set also had a loose plastic connection.
When the plastic piece fits tightly, this power filter is excellent. I love it.
