This product is great!
I use this glasses cleaner for my new glasses....the same one my eye doctor gave me when I picked-up my new glasses.  I loved it so much that I hunted on Amazon for the same thing!  It's great!  No smudging, no film left, etc.  I put the small one in my car, along with the small 'cloth' to use with the spray.  I had a couple  small spray bottles which I filled, one for my bathroom and another one for my office.  I'd recommend it everyone!
