Hi,
I have no problems with mine. Quality is good, not great. I have had that tank ( 50g cube) for almost two years, cannot complain.
Customer service is a joke, it took them around three-four weeks to deliver my tank.
First they wanted to send me 40g tank, who knows why.
Then the package got lost, they could not locate it, apparently it was on some train, but they did not know where.
They found it when my wife sent them an e-mail stating that we would cancel our order next day if they did not find it asap.
And no instruction how to set up their stand, absolutely horrible pain in you know where.
But overall good product

I have my thread with few pics on the "other" forum, you can find me there under "danielp".
Or you can stop by if you want to see it yourself.
