Never had a failure on the use of these for making Natto. Arrived and was in good complete order.

Clear directions and worked great to make natto.

This is a great product that I’ve used consistently over the last few weeks. It makes beautiful and tasty natto. This last package had one of the spore packages open on the bottom so when I shook the package to get the spores away from the top it dusted my kitchen floor. The other 3 packages are fine. Maybe there is a way to do a check before mailing? This is a very good product and I will continue using it.

I tried two times.I had sterile equipment. Filtered water, no chlorine. Properly hydrated and cooked beans. Temperature regulated environment, not less than 100 F no more than 110 F. Proper aeration.On the first batch I was seeing no fermentation and the beans were acquiring a bitter taste. I added an extra packet to that batch. Still nothing.Second batch, smaller, was even more careful. Between 105 F and 110 F.Neither developed natto's signature taste, aroma, or slimy, stringiness.This product is bogus. Don't waste your money.I'm going to try a natto bean powder which users have said is still active and can make natto (available here on Amazon) and frozen natto from a local Asian food mart.Very disappointed.

If you follow the directions, everything should work fine. My first 2 batches failed my third one came out better, I guess because I increased the temperature to 109°F, body temperature didn't work with my yogurt machine on it.
