J,
Funny you should mention those...
I bought some from TV and when I got them I was rilly PO'd, 'cuz the magnets did not line up... sent them all back, with a RUDE note.
Just bought 1 set at BB&B the other day, opened the box and checked them out first!
That is what I am installing into my sliding screen frame (as we speak), I will let you know how that works out after my little 'princess' works her magic.
