Here is a pic of Tray # 17 (bottom) compared with tray # 1 (top)....
I am AMAZED at the difference!!!! Its not until you actually take pics and compare that you can really see it working!!!!! YAY!!!!
Anyway, this set (#17) was very sore, the top tray when I first put it in was soooo sore that I actually had to take pain killers!!!! No pain, no gain right!!??? :)
