For two weeks they sold Coffeist without knowing the manufacturing process burned off the Vitamin A and C. They promised an update via email to customers but instead posted a blog update, while re-labeling and selling the remaining product at full cost.
The last instance of mold occurred just last month inside and out of sealed 2.0 bottles. Machinery leaked mold before the bottles were wrapped. Numerous customers and several batches were contaminated - with no contact from the company.
Other problems have included varying consistency from batch to batch and formula changes of viscosity without warning, and then the claims from users that have found roaches inside of the Soylent-branded boxes containing the bottles (not inside the shipping box).
The problem here is their approach. To discover this information you have to be connected to the community and keep yourself fully up to date or else you may find yourself unknowingly consuming a tainted batch. So far Coffeist has been the only instance in which they reached out to customers, despite there being several to many contaminated batches of their entire line - from bars, bottles, and powder.
The whole point of Soylent is that it's convenient, worry-free, and nutritionally complete. When I have to vigorously check my bars or bottles for mold, improper mixing, or to see if the expiration matches a contaminated batch - it's no longer convenient or worry-free. When they don't know for two weeks that manufacturing burns away the vitamins - and they re-label to sell it at full cost - it's no longer nutritionally complete.
"If you notice you have a bad batch, contact us," is not the approach I can trust for a new contender with no market trust. For a company that totes 100% transparency, they need to work on their customer outreach.
