I’ve owned 8 reef wave 45s. 5 failed within two years over the last 5 years as I’ve upgraded tanks, which I replaced the motors for a wonderful $150 each.
Reefmat 1200 owned for 6 months and just replaced that motor with a new one from Ali baba that was $15 compared to the $50 they quoted me...
lol I have had three of their tanks ranging from g1 to g2. In fact the only product that stands out to me that I haven’t tried of theirs is there reefled.
So the answer to your questions is that I am very qualified in my assessment of their products.
They suck.
It says in the site the amount you can order at each price point. Why does that prevent someone from ordering that many?
Of course group buys exist, they are not mutually exclusive of ali express.
