Virtual Tours on Listings....Yes...or....No?

I am curious as to how many potential buyers really look at the virtual tours that some agents provide on their listings. I know that several years ago when I was searching websites looking for the perfect home I had the tendency to avoid virtual tours and opted instead for listings with lots of pictures since the tours seemed to load up soooooo slooow. Then if I did load it up the scenes changed so slow and many times were only slide shows, no panoramic shots that I know can be created with the tours. Even now since becoming a Realtor® I still sometimes pass up the tours, especially if I click on the link and it doesn't load up immediately. I would like to know how others feel about this service provided to sellers for buyers searching for homes on the internet. Good idea or not?
