Rated 3 out of 5 by from Grew well... a titer would have been nice Bacteria grew as expected, however I was a little disappointed a titer was not included in the materials sent. Had to figure out on my own... but turned it into an educational opportunity, so all was fine in the end and there were indeed plenty of bacteria. We calculated about 3x 10^8 cfu/ml by the way...

Rated 4 out of 5 by from Grew very well I got the vial in good shape, left it overnight, and was able to get really great growth. Just using a cotton swab produced fairly small colonies but using an innoculating hook spread out the bacteria and I was able to get almost full coverage. I’d definitely recommend.

Rated 4 out of 5 by from Great results ! We used this for a middle school experiment . It was very easy to use and without any mess. It would have been nice to include clear instructions for storage of the product - we refrigerated it briefly by mistake but it still worked out.

Rated 5 out of 5 by from Good Strain of E.coli that grows Bought this product for a very important research paper for my school and everything went smoothy. Received the product in good packaging and nothing was leaking. The bacteria grew successfully and I did not encounter any problems with it.
