Does anyone here use Seachem Pond Prime?

I never new that seachem made a pond prime and after looking it over it seems to be almost the same thing as normal prime but it would last a lot longer due to the product being made for large volumes of water (like a pond).
Does anyone use this stuff? I think it would be a good way to save some money.
Here is a write up of it:

This may be a better way to go:

Pond prime is rated at a higher concentration than regular prime, so keep that in mind when dosing. Other than that, it makes no difference if you use it on an aquarium or pond.
