I bought this tank a few weeks ago. The tank is just OK - one of the glass panels on mine isn't set good and is 1/8" inwards at the top. None of the panels are perfect, nothing is completely "flush" on the edges. Mine also has a small scratch/dent on the same spot on all four sides. It's not perfect but it's not horrible either ... it holds water and is low iron. If you're a perfectionist you may want to look elsewhere. I think Finnex needs to improve there manufacturing process in my opinion for their tanks.
I got mine form aquavibrant as well as the lid is a nice bonus - no complaints there.
The light is awesome 5/5 stars.
This is considered a "medium" light by the majority. Some may say "high". I have no CO2 and just dose Excel daily (just under 1ML). No algae problems, water is crystal clear. Without Excel you will have algae galore though.
Maybe mine was just a bad apple, however I didn't want to deal with returning it as I had everything ready to go when it arrived. It looks good, no one will notice the imperfections except me. The tank get's a 3/5 stars and the light gets a 5/5 stars - overall 3.5/5 stars. Would I buy another one if I wanted another cube? Maybe, or just buy the light separate and get a Mr. Aqua cube.
