Let's discuss a few areas that have posed challenges. Firstly, the voices available are not consistently impressive. While there might be a couple of usable ones, they don't sound entirely natural. Additionally, I encounter a limitation when pasting text into the software – it doesn't allow more than 2000 characters, roughly 8-9 lines. This restriction feels quite low.

Another point of frustration is the inability to replay generated voices immediately. Every time I want to listen again, I have to wait around 10-15 seconds for the tool to regenerate the voice.
Despite having the tier 2 unlimited subscription and not worrying about credits, these issues make the experience very frustrating. I'm considering keeping it, hopeful that improvements will be made within the return window, but for now, working with it has its challenges.
