Query: Works well...but it's S L O W

I had read about evacuators on a few forums - it works as described. No complaints other than the amount of time it took do draw 8 quarts.that said, perhaps the first use included a bit of a learning curve.The fill/drain capability looked appealing, but if you don't need to use this device to fill fluids, I would opt for the drain-only device - less moving parts, fewer things can fail.
