Truly awful experience. Several emails with photos and calls to determine whether the installation was standard or not still failed to establish all of the prerequisites for the installation so I had to dash out to get a part when the installer arrived. He turned up with the wrong pod point products so didn't install what I had ordered. He made no attempt to clean up after his work, leaving self tapping screws strewn all over the garage floor, each one a potential puncture. Again, numerous emails and phone calls in the hope of getting the correct product installed. Three months later I am still waiting either for the products I ordered or a refund.
