Received these plates a few weeks ago and waited to write this review. I used 8/10 plates - After a week all 8 plates are showing great growth with no contamination at all. The two unused plates have also shown no sign of contamination. The black charcoal makes for a nice contrast with the mycelium. Plates are not shipped sealed individually but are shipped wrapped up together so as long as you properly sterilize everything before unwrapping you shouldn't have any issues. Great choice will order more.

Got these fast! I've used AGAR from ETSY sellers and these are by far better. Whatever they use in these really promotes the Rhizomorphic growth that I was not seeing with other plates, using the same source plates/samples. I would still suggest new AGAR users to use the regular colored plates at first but once you know what to look for, these are great!

Great contrast! Love this black! Good price! fast ship

Always love midwest's products. Got some rapid rhizo plates as well. Im new to agar but i have zero complaints once again with midwest.

 

I made an error with inputting my address and the team was so helpful every step of the way with getting that issue rectified even though weeks had passed since the delivery estimate. Anyway, once that was solved, my order was shipped out and I have had no issues whatsoever with my product. I love the great customer service that accompanies their reliable products.
