Has anyone used Tianbang shrimp feed, and how well does it work for shrimp farming?

Recently a Tianbang salesperson pitched their shrimp feed to me
What he said was quite tempting
But since I have never used it before, I still feel unsure
Can any brothers who have used it give some advice?
--------------------------------------
It is generally okay, no major problems will occur.

You can look into what brands of shrimp feed are available on the market now and make a comparison.

Good and bad are only revealed through comparison
--------------------------------------
Doing comparative trials is the fairest for everyone,
Remember to share the farming data and analysis with everyone when the time comes!
