So fill in the blanks 
So what is so good about it? What kind of media does it come with? How is the maintenance? How often do you need to replace the media? How often do you need to clean it? what's the pros and cons? I mean it can't be 100% foolproof..there's gotta be some flaws no matter how minor it is. For all we know you are marketing this product

Not sure if you were addressing me on this - go do a search on this site and find out for yourself ( no spoon feeding here, sorry). More than enough info is posted on this filter
(just type "Fluval fx5" or Fx5). You got moderators and established members giving high remarks about this filter. The feedback is 100% and extensive so go ask them if they are marketing the product too - LOL
You completely misunderstood the post I made. It is not an attack but a question as to why it is SO GOOD! Just because someone say it is "VERY GOOD" doesn't make it good. When you post something about a product, usually, you would make valid objectve points as to why it is a very good product. Just saying it is GOOD does not justify the product being good. And I have search the net about information, and most of the data I found are just based on the martketing ads. I have not seen an objective rating on this product, mostly subjectve. So before you start a crazy post, look at the big picture. Inhale, exhale. Oxygen helps to keep the brain thinking clear. 
By experience don't you become subjective? If the product works as intended for him/her and then some, how could one not become favorable or subjective?
