We love our glass peel and stick tiles! Cutting the glass was tricky but once we got a fill for cutting the glass it was good. I would suggest using a good glass cutting kit. The splitter with rubber edges worked wonders! The adhesive backing was also easy to work with and so far so good all the tiles stuck great! Our wall did have two places that bowed from drywall imperfections. So I caulked around those tiles just to make sure it filled in the small space. The quality of the tiles was amazing! And the color was exactly what I was looking for. Thanks wayfair! The whole backsplash took my dad and I approximately 2.5 hours and we had 6 whole tiles left over from our 2 boxes. I would totally recommend.
