Older product, different concept? Nailmates & Nail Savers

Came across this review for Nailmates on Manic Talons and thought these looked similar to these Nail Savers nail protectors I used to use while tanning.  Not sure about the size difference, but I'm curious to compare the two.  I will be ordering the Nailmates and will find my old Nail Savers for size difference.

The concept of using the caps to remove gel polish looks easier and less messy than the foil method and you can reuse Nailmates for several uses, that includes the caps and the nail pads.  Saving time and money, I'm sold.  Think of all the waste every time you use the foil method to remove polish.
