I been using them for years, They last a long time.

I like the items that they sell. I like the items that I ordered. I like that I’m able to call them and put my order in & within two days, it arrived. everything works. great people on the phone. nice and courteous. keep up the good work. love shopping there.

Great prices!

One of the best customer service experiences that I've had. Thank you pet guys

These are the best filters that I've ever used.

Was able to buy 12 of the filters for the price Amazon had for 6.

Fast shipping and handling

Not available in national popular pet supermarkets at double the cost. shipping charges okay!

Housing a Beta in your cookie jar? This small filtration system, low maintenance and very effective, will keep your Beta alive for years to come. I switch out the filter once every two weeks, and it works just fine. (I have four fish in a glass cookie jar -- including one huge Beta.)

The item is exactly what i was looking for and arrived very fast...

Can't find yhese filters anymore. The filters work great with my inclosed tank. My tank lid won't allow any overflow filters on any filter that need an above surface. with these filters al you need is a flat surface in the tank and an air pump.

I have used Smallworld replacement filters for several years in two small 2gallon tanks. They do a good job, are easy to change, and most other filters are too large.

These filters work wonderfully!

I love these I have used them for years

Very good value, fast service they even called me on the phone to clarify my state, will recommend and will buy again from the guys.

Acceptable. As described, good price, and arrived at the house quickly.
