There used to be a trial period, but peeps were abusing it, so it was removed like 5 months ago. There are almost 600 satisfied customers though, if you'd like to have a chat with any of them. The bot also has a 15 day money-back guarantee on the terms laid out in the bitcointalk opening post (if the bot has a bug etc. that causes you to lose money) you get your money back.
We have our own forums as well, feel free to check it out:
