FYI you can manually shorten amazon URLs which makes them more readable and gives amazon less data to work with:
https://www.amazon.com/dp/B017U0GCSQ
This link takes you to the same product. All that's needed is the /dp/ which I think stands for display product, followed by the 10-character set of letters and numbers that is associated with this item. Good find, by the way.
