Hello Azreal,
Yes it is true that we are a relatively new company but we are committed to providing great customer service. We are continually adding to our dealer list so we are growing steadily.
There have not been any issues with the shaft drive from those that have purchase our Penza. In the case that there are issues we do stock them with our manufactures so they are accessible.
Please don't hesitate to respond should you have any other comments or concerns.
Regards,
Mike
