Renting is a good idea, one day might not be enough time to figure it out. Be sure to read up on its use first.
The TS-E lenses are great, be very careful that you losen the lock screw before tilting, it is the number one cause of damage to this type of lens. The lock screw does not need to be very tight, don't over tighten it.
My product shots with the TS-E 90 are mostly gone, or Lightroom cannot find them. The exif reporting for it is weird, it depends on the camera body. I have a folder of test images, but lightroom cannot read the exif.
Here is a shot of a camera lens, not very small, but you get the idea
I do not recall if or how much tilt was used, there is no tilt information saved in the metadata.
