I bought the bot and gave it a try. Think its not really worth to pay 5$ for 5 days when there are free bots around providing nearly the same. But was fun testing the bot.
At least that has answered your curiosity and I don't think $5 is a big amount for an experiment. Regarding free bots, please be careful because they can contain viruses and you must ensure that the dice website you are using to play allows the use of bots otherwise they will block your account and you will lose funds there if there is.
