My 2 year old got one for Christmas from grandma. She paid $99. I paid another $100 to get it going. I needed the heater, net, decor, replacement media, vacuum, chemicals, algae brush, etc. And of course, Fluval is more than happy to put "Edge" on all that stuff but not include it in the box. Even the "Edge" heater cost like 29 bucks. That's a third the price of the whole kit.
I opted for spongebob decor for the 2 year old and not the "Edge" decor for another $30-$40.
As for a review, I'd say it is what it is. Nothing special. I guess having a glass top is unusual. The filter that comes with it is enough so suck a neon up in to it. (oops).
I would not have bought one but since it was a gift I guess it's okay. The best part about it was it got me back in to the hobby. I'm up to a 125g now but it started with setting up that 6 gallon 5 months ago.
