Hi John
Just like anything out here, you are going to find people who fail and people who succeed. SBI! is no different. You just have to go into with the right expectations and attitude.
1) Be prepared to do a lot of reading/learning in the beginning
2) Success is not instant for most people but definitely possible if you work hard and follow the guide you will be given
Overall, I think SBI! is a great system but success is definitely not guaranteed. How well you do with the product, largely depends on you. SBI! will provide the tools but you have to bring your own creativity and hard work to the table to complete the process.
