Review on PowerTwist V Belt Profile Width Length Power Transmission Products by Dan Bobbert

I bought these for my drill press after making some modifications and the standard belts no longer fit. Installation was easy. It only took a few minutes to determine the required length and connect them together. Can't say I've noticed any noticeable improvement in ride before, but I've had quality belts before, so it was already running smoothly. I've heard from some friends that they can make a big difference on certain hardware. They seem to stretch a bit over time. It only takes a minute to remove a link and you're back in business.
