This was the first time I ever installed glass tile and it was a lot of work. I tried different tools and the best was the QEP professional tile cutter. Make sure you get the glass oil, I didn't so I used olive oil lol. The product was very good quality and was packaged very well! Glad it was peel and stick and it stuck to the wall very well! I used a butter knife if I needed to adjust the piece and had no problem re- sticking it to the wall. I had neighbors very impressed with the quality of the product and that it was a peel and stick. I plan on using the same product for my bathroom projects. I am very pleased with how it looks and the quality!
