I bought these for our yacht because water from the kitchen sink was splashing up onto the teak backsplash.  They are easily cut with scissors and are holding tight.  They were an inexpensive way to jazz up the backsplash without using adhesive and grout which would eventually fail.  I don't think they will be too hard to take down "when/if" I decide to change to a different color.  Great product for boats and Rv's that are in motion.

Pros: Easy to cut and install
Cons: Doesn't look like real glass tile - a little plastic looking, as expected.
