I would also add code quality and Customization to this review. Bought and tried another support system after looking at all other and I wish I had really looked much more at this one first. Best Support System really does it all and much of the code allows for great alterations and after that it does even more. No bugs and no issues on php8.1. Good simple UI. Ease of email piping to application.

Definitely bookmark this if your looking for a good ticket support system and knowledge base. I think it may truly be best.
