https://twitter.com/uberrimedildos Has worked multiples with SheVibe to do really questionable things, such as steal a design from a defunct shop "if they return we'd happily credit/pay" and then design an extremely sexualised and offensive trans fem toy. Probably some other stuff I'm not aware of, but these two seem to share the same mindset to keep doing stuff like this.
https://twitter.com/bad_dragon Extremely long problematic history from things like morals to things like terrible QA, unsafe toys and customer service and so much false advertising.
https://twitter.com/Weredog Partnered up with BadDragon and adopted their company policies. I don't know of any issues just generally lost all respect since they decided to partner with BadDragon - a company that puts profits first over customers.
https://hodge-podge-entourage.com/ Had several issues in the past with handling communication, feedback on QA and safety practices. I haven't followed them since those issues so no idea how things have changed. People otherwise seem happy with their work.
https://twitter.com/MoonFoxToys Overall toxic interactions with community, issues with QA and showing real pours at the start - they only showed 3D renders. Just, not really great track record.
