Yeah, just like every brand of CD/DVD in the world is manufactured exactly the same in one of very few factories. The exact same disk, manufactured in the exact same factory, can have hundreds of different brand names.

I don't know man. I checked two of those coralife thermometers against USDA checked and calibrated thermometers. Neither one of the coralife thermometers was accurate. Way too far off for my taste. They're only close at room temperature. The higher or lower the temperature goes beyond that, the farther off they get. At 85 degrees true temperature, the two I bought are reading 90-92. At 60 degrees, they're reading 54 or so. It's that bad. You get what you pay for.
