Interesting device. Now you have been on ebay for eighteen years and you don't see how many views are on an item? Pretty hard to believe. Ok, now I see that your selling feedback is (12) and all of it is over a year old.
Since you don't have a store I am not sure how the pages look but from the Seller Hub I click 'Listings' and one of the columns is VIEWS.
Plus when I click on any of my 3100 listings the view count is right at the top of the page. That's just for the seller to see.
