they also have "Aqua tech" filters which are a cheaply made penguin filter without bio wheels. they have them for 55 gallon tanks and smaller.
The heaters that I have from Walmart are pretty terrible; as said before, there is quite a bit of variation in the temperature that they maintain.
Surprisingly, my Aqua Tech filter from Walmart is much more reliable than my Penguin filter; I have had fewer problems with it than I have had with the Penguin. Of course then, both filters are nothing in comparison to some of the other filters on the market.
