K know I'm late to the party.
I have one of these. The light for the 12 gallon Edge is a bit more bright. It's not high light by any means, but it does help some.
For pros: It looks really nice. I have mine with black sand and some plants. I have java moss, a crypt, an anubias.
Cons: You can't keep very many things in it. Shrimp, a few snails. I've kept 3 black neon tetras in mine for a long time.
If it's not level, you will get a bubble that you need to get rid of with a class cleaner after you fill it back up.
If you are looking to use a sponge filter instead of a hob, then you will need to put it the middle of the tank. It might look neat, or awful, depending on what you do with it.
It can be heard to work when you want to plant something and for cleaning.
