With the structure of my website, the default Joomla breadcrumbs was not providing me with the correct layout.
I purchased this product and it works exactly as i hoped. It took some custom php (which is easy enough to put into this component), but the developer seemed more than happy to help.
I do not purchase many commercial components, but i would purchase from this developer again in a heartbeat.
Unfortunately, i am not using even a fraction of the functionality that this component has, so its not possible for me to comment me on much.
But i don't think that you could ask for better developer support anywhere.
