After just a few weeks of light use (morning coffee), everything began to smell like "dead fish." At first, I thought it was the water supply. But no, the incoming water was fresh and clean, but after putting it through this filter, it tasted and smelled like dead fish.

This is obviously a poorly engineered, poorly executed design that is not only worthless, it appears to be harmful as well.

Keeps my dog's breath from smelling like rotten fish.  Now it just smells like fish.  I can live with that.  Plus he loves this stuff.

Smelled so much like chemicals! I rinsed it well and tried it in the water for 5 minutes. The whole tank smelled like a chemicals. I took it out and the water continued to smell. I added some start-right and it cleared up after the tank cycled. It looks so cute so I put it as a decoration on the outside of my tank but the whole room started smelling like the chemical that I just threw it away.

I'm only giving this 3 stars because other people say it worked well for them and I haven't used it long enough to know. My problem with this is that the fish smell is sooooo strong that my dogs take longer to decide to eat and my cats won't come near it. It really does smell bad. The other problem that I have is with the bottle, with or without pump, it makes a mess all over the bottle. The pump keeps leaking long after I have finished using the bottle and it seems impossible to just pour a small amount out without it running down the sides of the bottle. So I will get another brand that clearly says it doesn't smell and hopefully the pump works.

Although it may smell as bad as rotten eggs this stuff is soo good for the fish and bring a more beneficial ecological edge that you maybe missing in your pond

I am not necessarily endorsing Bang. Scent works better than no scent. Fish taste it, like it, and tend to hold on a bit more allowing for a better shot at a hook set. It's that simple, though temperature does play into it. Scent in warm water disperses and can have fish looking all over for the bait, whereas in cold water, 55 degrees or colder, water is thicker, until it goes solid at 32 degrees, thus the scent trail is more helpful and tends to lead fish more directly to the bait. None the less I tend to use it year round as I do end up with more fish when I use it. That said, if another reputable brand is less expensive I'll buy it.

It was longer than I expected that was pretty cool amnd it had scratches on the metal balls and it is light. I ccould over look any of the cosmetic issues I saw but I can't deal with the smell. It has a gross fish market odor like when your at the store and there's raw fish on ice yeah that smell.
Sorry but I can't use this on my sub's so I asked for a refund.... Your better of making your own.

The water is great when the filter is fresh.  After a while the water gets a strong fishey smell like a gold fish bowl.  Also the base of the filter case near the spout is too weak and cracked causing a leak.  the walls need to be thicker and maybe a turn spigot would be better.  Having said this I ordered the pour filter 10 cup model as the fresh water is very good.  So far the best tasting filtered water that we have tried.  Including Berkley, Brita, and Aquasana as we have tried all of these.  We travel with the Berkley in case of an emergency situation in our RV but like the Zero Water the best.  They just need to beef up the container a little and look at why the filters put out the fishey smell after a while.  The smell is strong enough that you can smell it in the kitchen area.  Like you are preparing fish or shrimp to cook and not all filters do this just certain ones.  Other ones eventually make the water taste bitter after a while ?

Has a strong rubbery smell. Haven't tried soaking it in soapy water yet. Works well, though.

Edit: soaked it in soapy water for over a week and it still smells as much as when I got it.  I'm taking this down to 1 star because the smell might make you sick since it's so close to your face when you use it.  Get a different brand instead!

Smell isn't terrific,  but sure helped clear up my pond water. Didn't effect my fish at all!

Good concept. The initial taste was good, but sadly the after taste was what fish food smells like.

Smells Good.
Kills silver fish. Not sure if it is effective on their eggs.

I have never used this for water. Instead I store one in my deep fryer to help absorb the food smells and tastes out of the oil. I was very unsure if it would work, afterall it isn't what it is designed for, but I was pleasently surprised. In fact, I was so shocked at how well it obsorbed the odors that I bought a couple more for when it is time to replace it. So far 1 piece has lasted me almost 6 months, after the 6 months I will put in a fresh one. Totally worth it!

My husband is a fishing guide, he cleans fish for customers daily. I had him use this to no avail. He still smells like fish

Horrible smell to this case. My husbad opened and used this case so it was too late to return. The horrible fishy odor will not go a away. Renders it unuseable
