Got a Fluval Spec 5g and I'm unimpressed with the construction of the light. It droops unless you wedge it correctly against the tank to get the right angle. The plastic screw that "screws" the light to the holder is absolutely worthless. It strips against the metal and doesn't hold at all. It's basically a useless piece of plastic.
I was slightly unhappy to see some minor scratches on the glass. I expected FLAWLESS glass. Is that an unreasonable expectation? I'm pretty picky as well.
The filter was a bit hard to wedge into the cavity, and the power cord doesn't come out of the filter at the right angle to get the filter wedged down squarely. I was very impressed by the size of the filter sponge they have for the filter. Filter seems to work well, good flow. Although too much flow for my betta.
Was excited to post some unboxing pictures but then got lazy and I see that xenxes beat me to it. Ah...
