This was the correct belt for my Shark Euro Pro V15Z hand vacuum. I replaced my old belt which had been stretched out with one of these and now it works!
I haven't had to change the bag in my vacuum yet, but it appears to be easy enough and I like the fact that the hose end to the vacuum unit does not have to be removed in order to change the bag. This is another reason why I don't like the ProLux Terra Vacuum, very hard to replace the bag.
