Anyone ever use Safcider and see a really fast fermentation?

Put it all together on June 1st. Almost one gallon of pineapple and mango juice, about 12 oz of agave nectar and a full 5 oz packet of this stuff https://www.northernbrewer.com/products/safcider-5g.
Come 5 days later there doesn't appear to be any fermentation activity. I ask the guy who sold it to me and he says that it's probably done fermenting. I check the gravity reading and it is actually reading less than 1.00 after an initial reading of somewhere around 1.10 I think. I can't believe my eyes. Anyone else have a similar experience????

What was the temp?
I like Safcider, but my experience has been must slower. But also the temps were in the 60s.

I didn''t temp it, but I''m guessing it was somewhere around 73-80 F.

That might explain it.

Would I get a better finished product if I fermented at a lower temp?

Most likely yes. The warmer, faster ferments often stress the yeast, so they produce odd flavors that have to age out, hopefully, over time.
