Those are some nice looking bay reservoirs. And I especially like them because they are small. Are people finally waking up that smaller is better? I've known that for 10 years.

But one thing I don't understand is when companies call products "professional". What does that even mean anyway? Professional what? Professional like a doctor or a lawyer? Professional like a hitman? Professional like a prostitute? Professional vs. "Amateur"? Dunno why, but I don't like the "professional" moniker, because it seems like overselling, or just plain hype, (like "turbo" computer components), or gilding the lily, but this is not a knock against these reservoirs, which look great BTW, it's just an observation about the increasing usage of the word "professional" generally.
